Option to highlight major version updates

[joaonc]

Is your feature request related to a problem? Please describe. Currently when the remote version is newer than the installed one, it shows up in red, which is great, and we see that in the example below.

In this example, the pyparsing package has a new major update: 3.x, as opposed to a 2.x installed.

👉 The request is to have a different color (ex brighter red) if the major version is newer than the installed version.

I understand that this may not mean much in projects that follow a different versioning strategy, but would be helpful where major.minor.patch is used.
