feat(updates): add possibility for custom value postponing updates

[AnonymousWP]

Is your feature request related to a problem? Please describe.

I wanted to postpone updates, but noticed it's either delaying features updates by two years (way too long in my opinion) and delay security updates by 4 days (sounds good) or disabling it altogether. See screenshot.

Describe the solution you'd like

I'd like a feature that either allows me to set custom days for feature updates and security updates, or a 4th option that has a shorter time (like 2 months) for feature updates.

Describe alternatives you've considered

Set it manually via gpedit.msc, but then I'll have to find out. Rather have 1 program to do it.
