Consider vPrefix when retrieving the latest semver tag.

[k1LoW]

Hi @Songmu.

I am currently operating a repository with a mix of "semver with v prefix" and "calver without v prefix".

$ gh release list | cut -f 1
v1.1.2
v1.1.1
2023.05.1
2023.05.0
v1.1.0
v1.0.1
2023.03.1
2023.03.0
v1.0.0
2023.02.0
v0.1.0

At this time, tagpr may misidentify calver as semver.

If tagpr could determine the vPrefix setting more strictly, it would avoid the misidentification, at least in my environment.

I hope you will consider this change.

Thanks for the quick merge!
