[feat]: Tidy up releases and tags into a standard format

[digiserg]

As we haven't released a version yet we've been careless with tags and versions. As part of this feature we should:

• Remove all existing tags
• Remove all existing releases
• Create a new beta1 pre-release
• Add enforcing rules for:

v1.1.1 -> main release
v1.1.1-beta1 -> beta pre-release by default
v* -> anything else always pre-release
