Color code the Spring dependencies in the detail and dependency frequency views

[pacphi]

It would be nice to provide a red-orange-yellow-green color coding correlated with: completely out-of-date, nearing end of support, in-support, and most recent Spring versions detected.

E.g.,

For versions of Spring Boot detected

Green is 3.2.x
Yellow is 3.0.x to 3.1.x
Orange is 2.7.x
Red is < 2.7.x

We'd similarly color code for all other Spring projects in eco-system we wish to report on.

We'd want to manage project-version mappings externally so we could adjust independently of build-packaging.
