[chore] Update gorilla/websocket

Description

The maintainers messed with the v1.5.2 tag which causes Go checksum validation problems as the Go module proxy saw and recorded the original hash.

This updates to 1.5.3 which doesn't have the issue.

we already closed this one as it basically back-steps a bunch of their changes: https://github.com/superseriousbusiness/gotosocial/pull/3036#issuecomment-2185904981

Yeah, but I actually think those are good.

v1.5.1 was released after the project was effectively unmaintained, and included a bunch of unreviewed changes. v1.5.2 seems to have been stepping that back and adding new features and fixes of its own, now with proper review. Dhey botched the tags so we got v1.5.3 to fix that.
