Show support for current Nova version

[RhysLees]

This PR adds the following:

• nova_version to packages DB Table

• Nova version to PackageDetailFrame if their latest stable release requires a Nova version

• Current Nova Version Supported Label to Package cards if their latest stable release requires a Nova version that matches the major version specified in env

• Adds Nova's current filter to tags and filters their latest stable release if it requires a Nova version that matches the major version specified in env

When a new major version of Nova is released all that is needed is to increase the version in .env from NOVA_LATEST_MAJOR_VERSION=4 to NOVA_LATEST_MAJOR_VERSION=5

Closes #196

@marcusmoore Is there anything else you think should be added?

[RhysLees]

@marcusmoore I can also close #63 with the same type of tag instead of saying Potentially Abandoned Would it be worth adding to this PR or as a separate PR?

@RhysLees thanks for the updates and also peeking at additional issues that might be solved in a similar manner. A separate PR would be appreciated.

I'll review (and hopefully merge) this PR later this week.

Thanks again! 😄

Awesome, thanks for Reviewing, I'll wait until this is merged then I'll make a PR for the other issue as it mainly uses the same code from this PR 😊
