packages: add ignore_updates_regex

[MaxVerevkin]

We already have warning_updates_regex and critical_updates_regex. A new option can be added to filter the list of outdated packages.

• Apt (blocks/apt: Added config option ignore_updates_regex to filter the list of updates #1967)
• Dnf
• Pacman

For pacman wouldn't you just want to ignore the package in pacman.conf? What would be the benefit of ignoring it in the status bar, but actually updating it when you go to update your system?

I imagine other package managers have similar configs that allow packages to be ignored.

I have some -git packages installed from chaotic-aur which are updated multiple times a day. I do want to keep them up-to-date, but in context of status bar, these packages generate a lot of noise.

Hello @MaxVerevkin !
I've opened a pull request to add this ignore_updates_regex option to blocks/apt: #1967
Please have a look at it :)
