feat(init): various fixes/improvements

[Gankra]

• new target selection UI
• if you have Github CI enabled, we won't ask anymore
• if you have pr-run-mode set, we won't ask anymore (we also no longer omit it from output when the default is selected, so that we can distinguish new init from made-a-decision)
• extra unimportant words removed
• if you have no CI backend enabled we will still allow you to turn on msi
• we will always run generate at the end (unless --no-generate-ci is set) because generate now detects which parts need to run on its own (and the current logic was preventing CI-less MSI from working).
• [profile] de-emphasized, sent to the end, not mentioned if unchanged

Here are some screenshots of the 3 main init workflows. Each screenshot is a spot where your are stopped to make a decision. The displayed value is the the one --yes would have selected. I always press enter, getting the same result as --yes.

First Init Workflow

This is a True Init, where cargo-dist wasn't setup at all.

final output:

Upgrade Workflow

This is someone running cargo dist init to update to a new version of cargo-dist. In this case they are prompted to setup the new pr-run-mode feature:

final output:

Up To Date Workflow

This is someone running cargo dist init with an up to date cargo-dist. In this case they're either looking to change targets/installers, or just want to run generate.

final output:

Got tired of seeing the [profile] stuff so prominently, so I removed it completely from the top, and now have it only show up if it's being made for the first time:
