fix(goreleaser): missing tendermint->cometbft update (#3083)

This one escaped the migration, probably because it's located in a
hidden file.

Note that this omission does not seem to have affected the releases that
followed the migration (at least for v15.0.2, which is the only one I've
checked), as `cometbft.TMCoreSemVer` is already equal to the correct
version (it's apparently updated manually during the cometbft release
process).
