Should tag-semver work without patch version?

[EnricoMi]

Some small projects might decide not to release patch versions but still follow the semantic versioning rules. Can this action work with tag-semver: v${{major}} on tags like v1.0 to produce v1? Currently, it does not seem to:

That's because v1.6 tag is not a valid semver:

2. A normal version number MUST take the form X.Y.Z where X, Y, and Z are non-negative integers, and MUST NOT contain leading zeroes. X is the major version, Y is the minor version, and Z is the patch version. Each element MUST increase numerically. For instance: 1.9.0 -> 1.10.0 -> 1.11.0.

Should have been v1.6.0 to be a valid one for example. I will add a warning message in case tag-semver is used but input tag is not a valid semver.
