feat(chore): align Makefile and goreleaser

[tbruyelle]

So make build, make install and goreleaser build produce the exact same binary.

The fix consists mainly of tuning the ldflags of the Makefile and of the .goreleaser file:

• arguments must be in the same order
• removed -X main.commit and -X main.date because this is the default ldflags of goreleaser and they were probably blindly reported in the customized version, but they are actually useless since there's no commit nor date field in the main package of the application.
• replaced tendermint/tendermint by cometbft/cometbft

A couple of other tiny things had to be updated:

• aligning the version name when there's no tag (snapshot.template_name in goreleaser and VERSION var in Makefile)
• fix Makefile VERSION var when there's a tag
• add CGO_ENABLED=0 in Makefile
• remove double quotes around the BuildTags ldflag because it's useless and goreleaser doesn't use double quotes.

Quick demo:

$ make build install   # produce build/govgend and $GOBIN/govgend

$ goreleaser build --single-target --clean --snapshot   # produce dist/govgend_linux_amd64_v1/govgend

$  sha256sum $GOBIN/govgend build/govgend dist/govgend_linux_amd64_v1/govgend

Didn't test this but code looks solid.
