Fix AppImage OpenSSL runtime

[bedlaj]

Fixes #420

The AppImage bundles libssl.so.3 and libcrypto.so.3, but it did not bundle matching OpenSSL 3 runtime files.

On Fedora this breaks websocket TLS handshakes with:
unregistered scheme (STORE routines)

This was visible mostly as Kick chat not receiving messages, because Kick chat uses the Pusher websocket. Kick login and stream preview still worked. Twitch basic chat could also still work, because that path does not depend on the same websocket.

Result binaries can be reviewed on my fork nightly release https://github.com/bedlaj/chatterino7/releases/tag/nightly-build
I have tested only Fedora 43, I have no acces to windows or other linux dists.

Code was AI assisted (codex)

Thank you for looking into this.

I saw other projects that use AppRun to set SSL_CERT_FILE. For example here: probonopd/linuxdeployqt#621 (comment). I'd prefer doing that.
