Improve the check-release tag parser to be more robust

Explaination

check-release.yml used to parse the GITHUB_REF with tr -d 'refs/tags/v'. But, tr deletes characters and not a specific string.
Which results in a wrong parsing of tags containings the characters present in refs/tags/v.
Example:
refs/tags/v0.1.0-strapi-v3.1 becomes 0.1.0-pi-v3.1

To avoid this issue, the command is changed to a more robust parsing method: cut -d '/' -f 3 | sed -r 's/^v//'

• cut -d '/' -f 3 splits our string based on the / and takes the 3th element.
  refs/tags/v0.1.0-strapi-v3.1 => ["refs", "tags", "v0.1.0-strapi-v3.1"]
• sed -r 's/^v//' removes the prepending v.
  v0.1.0-strapi-v3.1 => 0.1.0-strapi-v3.1
