`releaseDelay` instead of `stabilityDays`

What would you like Renovate to be able to do?

Get a flexible way to delay looking for new updates as commented here: https://github.com/renovatebot/renovate/issues/12133#issuecomment-943966256

Related issue: https://github.com/renovatebot/renovate/issues/12310

If you have any ideas on how this should be implemented, please tell us here.

The summary mentioned by @rarkins is:

• Rename it to be a bit more generic (e.g. "releaseDelay", but better)
• We retire/migrate stabilityDays
• Define a simple format for duration - or find one which already exists - so that it can be e.g. 1d2h3m. We might find use for such a format elsewhere

Is this a feature you are interested in implementing yourself?

No

We also discussed some new names for the stabilityDays config option in this issue:

• https://github.com/renovatebot/renovate/issues/12914

The name minimumReleaseAge from #12914 is maybe more intuitive

[rarkins]

The pretty-ms package converts from milliseconds to human readable string. I think we need to write the opposite, i.e. to convert from human-readable string back to a millisecond duration.

Now done: https://github.com/renovatebot/renovate/blob/main/lib/util/pretty-time.ts

Let's do it in a major release when we rename renovate/stability-days to renovate/minimum-release-age.
