Use conventional tagging for GitHub actions

[TWiStErRob]

I noticed you're doing v1.0 and v1.1 tags for releases. This is nice, but it means that people have to manually update their action references every time there's a release: uses: szenius/set-timezone@v1.0 -> uses: szenius/set-timezone@v1.1.

This can be easily solved by pushing a v1 tag to your Git repo (no release required) and force pushing that v1 tag every time there's a v1.x release.

• uses: szenius/set-timezone@v1 -> builds with 1.1 right now
• some time in the future you release v1.2 and update the v1 tag.
• uses: szenius/set-timezone@v1 -> builds with 1.2 immediately on the next execution

Hi @TWiStErRob thanks for the great suggestion! I'll do this when we move to v2 since I don't foresee us moving from current version for a long time.
