chore(deps): bump maunium.net/go/mautrix from 0.26.4 to 0.27.0

[dependabot]

Bumps maunium.net/go/mautrix from 0.26.4 to 0.27.0.

Release notes

Sourced from maunium.net/go/mautrix's releases.

v0.27.0

Slightly breaking changes

• (crypto) Changed GetOwnCrossSigningPublicKeys to return errors instead of only logging them and returning nil.
• (event) Removed automatic registrations of content structs to encoding/gob. If you use mautrix types with gob, you'll have to register the structs yourself.
• (crypto) Removed unused Olm PK encryption/decryption interface.
• (crypto/goolm) Removed unused JSON pickling methods.

New features and non-breaking changes

• (client) Added support for MSC4446 for moving m.fully_read backwards.
• (appservice) Added support for escaped paths in HTTP over websocket proxy.
• (synapseadmin) Added wrapper for redacting all events from a specific user (thanks to @​nexy7574 in #466).
• (event) Added types for MSC2545 image packs.
• (bridgev2) Added option to block automatic portal creation for specific chats and/or users.
• (bridgev2) Added commands to bridge existing groups to existing rooms and to create new portal rooms for existing groups.
• (bridgev2) Added option to always prefer default relays for the bridge and set-relay commands.
• (bridgev2) Added support for using MSC4437 for ghost profile updates.
• (bridgev2) Added optional GetStateEvent method to ASIntent to get state while respecting room membership.
• (bridgev2/mxmain) Added environment variables to change global values like the portal event buffer size.
• (event) Changed EnsureHasHTML to also ensure the body is treated as a caption for media messages.
• (bridgev2) Changed relay mode to treat stickers as normal images.
• (bridgev2/matrix) Changed various start methods to return ExitErrors instead of calling os.Exit directly.
• (client) Changed sync response structs to use omitzero instead of custom JSON marshaling functions.

Bug fixes

• (crypto/goolm) Fixed various issues.
• (crypto) Fixed new Olm session handling to only delete one-time keys after successfully decrypting a message.
• (crypto) Fixed ResolveTrust not checking trust status of cross-signing keys correctly.
• (crypto) Fixed m.relates_to copying not working for some inputs with goolm.
• (event) Fixed Content.UnmarshalJSON incorrectly keeping a reference to the input data.
• (format) Fixed math blocks not being routed to correct convert function.
• (bridgev2) Fixed sending tombstone when redirecting a portal to another room.
• (bridgev2) Fixed removed messages/reactions not being removed from database.
• (bridgev2) Fixed race conditions where portal ID changes could result in a duplicate room being created.
• (bridgev2/mxmain) Fixed some types of config fields not being settable with environment variables.
• (appservice) Fixed redundant mx_registrations database query on every request.
