Bump golangci-lint to latest version

[DimitrisJim]

Seems that running the linter (locally) with 1.57.2 leads to many new linting errors popping up, many seem to be due to not checking if a cast to a type is ok (x := y.(type).

We should bump the golangci-lint version in our workflows and address issues it brings up. Until then, installing and using 1.54.2 locally should do the trick.

I don't mind taking this if nobody disagrees :) I was already running a newer version and got confused by some errors :)

ay! sure thing, go ahead if you have time!

I definitely underestimated the number of errors shown by the new version :D I'll still work on this, but it's going to take some time :)

ahahah, no worries. This is def not too pressing, just annoying for people running locally. Take a good amount of time for it!
