Update GoReleaser config (#3974)

Changes:
- Updates the configuration to remove '--rm-dist' deprecated flag
- Changes extension of SBOM artifacts from .sbom to spdx.json to better
  represent the content of the file (.sbom is an extension that devs at
  GoReleaser came up with and not standard)
- Adds section to override the version that is injected in the binary
  for snapshot builds. These are all the builds that are not an official release.
