Update goreleaser.yaml according to latest version

With goreleaser version v1.14.0, archives.replacements and
nfpms.replacements have been deprecated and we can leverage their
respective name_template and file_name_template. Also the `replacements`
property has been removed in v1.19.0.

Updating goreleaser.yaml as per the suggested approach specified at
https://goreleaser.com/deprecations/#archivesreplacements
