Version Ranges: alias blang/semver

[tmshort]

Summary

The blang/semver API provider must be explicitly identified as such. The alias for blang/semver shall be bsemver or similar (this may change in the PR). When the Masterminds/semver API provider is introduced later, it will have its own alias of mmsemver.

• Update the alias from smever to bsemver.
• Add a golangci-lint check to validate that the alias is used everywhere.
