feat(libSceHttp2): export sceHttp2WebSocketSetPingInterval

Export sceHttp2WebSocketSetPingInterval (YfaXPnc8PJE) in libSceHttp2.

Resolves unresolved ELF import in Palworld (PPSA23126, Issue #2648) bundled libdiscord_partner_sdk.prx.

 - [libSceAudio3d](../../core/libs/prx/libSceAudio3d/Export.cpp) - the port produces no sound: objects can be reserved and `sceAudio3dObjectSetAttributes` accepts their attributes, but the library has no bed exports or mixing to give them audio, the attributes have no effect and `sceAudio3dPortPush` only paces the queue at `granularity` samples per frame at 48 kHz. `sceAudio3dPortSetAttribute` accepts the late reverb level and the downmix spread attributes and ignores them. `sceAudio3dObjectSetAttributes` validates the port, the reserved object and the attribute array (an object id that was never reserved returns the invalid-object error, while shadPS4 returns success for it and the error only for a released object; neither is measured on a console), treating the reset-state attribute as valid with a null value and requiring a value for the others; the attribute identifiers and the value of each are not interpreted. `sceAudio3dPortFlush` drops the frames queued by `sceAudio3dPortAdvance` instead of mixing and submitting them to an output, as there is no output
 - [libSceTextToSpeech2](../../core/libs/prx/libSceTextToSpeech2/Export.cpp) has no speech engine: `sceTextToSpeech2Initialize` fails and the other exports throw. PPSA01317 skips its narration set-up when initialization fails
 - [libSceAvPlayer](../../core/libs/prx/libSceAvPlayer/Export.cpp): `sceAvPlayerSetLogCallback` accepts a callback that is never called, as the player produces no log messages, and `sceAvPlayerSetAvailableBandwidth` has no effect, as it governs HLS sources, which `sceAvPlayerAddSource` does not implement.
-- [libSceHttp2](../../core/libs/prx/libSceHttp2/Export.cpp) - no request reaches the network, so `sceHttp2SetMinSslVersion` has no TLS connection to restrict and returns success for any `id`, like `sceHttp2SslEnableOption` (prosper returns the invalid-id error for an unknown one)
+- [libSceHttp2](../../core/libs/prx/libSceHttp2/Export.cpp) - no request reaches the network, so `sceHttp2SetMinSslVersion` has no TLS connection to restrict and returns success for any `id`, like `sceHttp2SslEnableOption` (prosper returns the invalid-id error for an unknown one); `sceHttp2WebSocketSetPingInterval` records no ping interval and returns success without network activity, unblocking Palworld (PPSA23126)
 - [libSceNpTrophy2](../../core/libs/prx/libSceNpTrophy2/src/GameInfo.cpp): `sceNpTrophy2RegisterUnlockCallback` accepts a callback that is never called, as no trophy is ever unlocked, and `sceNpTrophy2UnregisterUnlockCallback` only returns success.
 - [sceAvPlayerSetTrickSpeed](../../core/libs/prx/libSceAvPlayer/src/Source.cpp) (libSceAvPlayer) with a negative speed runs the clock backwards but delivers no frames; when a forward speed is set again, playback resumes from the rewound time.
 - [sceRudpActivate](../../core/libs/prx/libSceRudp/Export.cpp) (libSceRudp) - there is no reliable-UDP stack on the host to activate, so it returns success without doing anything, as [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/rudp/rudp.cpp) does for its own `sceRudpActivate`. PPSA01325 calls it with no arguments during start-up; what the console activates, and whether it reports an error before `sceRudpInit`, is unverified
