You can also use optional parameters tagRegex and tagRegexGroup to extract a part from tag string.
Dead simple:
steps:
- uses: olegtarasov/get-tag@v2
id: tagName

tagRegex: "foobar-(.*)" # Optional. Returns specified group text as tag name. Full tag string is returned if regex is not defined.
tagRegexGroup: 1 # Optional. Default is 1.
- name: Some other step # Output usage example
with:
tagname: ${{ steps.tagName.outputs.tag }}
- name: Yet another step # Environment variabl usage example
