chore: add changeset for xmtp update (#77)

[insipx]

Adds a patch changeset for the xmtp bump in #77, which merged before the Renovate Changeset workflow was fixed (#78) and so never got an auto-generated changeset. Without this, the next release won't capture that bump.

Mirrors what the action would have produced: @xmtp/convos-cli patch.

This PR only adds a changeset file for version management, which has no runtime impact and is purely documentation/metadata.
