Tag format

[erikbosch]

Currently we use tags of format X.Y. Many other actions use vX.Y, see for example https://github.com/eclipse-kuksa/kuksa-databroker/blob/main/.github/workflows/kuksa_databroker_build.yml , that seems to be standard.

Should we possibly change to vX.Y? Any opinion @SebastianSchildt ?

If we are to change a possible workflow could be:

• Keep all old tags of format X.Y
• Duplicate 4 and 4.3 as v4 and v4.3.
• For new releases just create v* tags.

I personally do not like "v" tags for purely subjective aesthetic reasons, but I really don't have a problem to change it here for the actions , if that is more common for "actions"
