build: update release process

[tplooker]

Description

Because GH Actions now appear to recognise the [skip ci] convention in the commit message, this cannot be used in the way we were using it for the release process. Hence the release process has been updated accordingly

• [ ] Tests for the changes have been added (for bug fixes / features)
• [ ] The commit message(s) follow conventional commits
• [ ] Documentation has been added / updated (for bug fixes / features)
• [ ] Changes follow the contributing document.
