Description

Since merging #4424 and #4483, it appears that dependabot has been having issues with our configuration. We're seeing this error everytime dependabot attempts to run on dependencies:

Dependabot encountered '1' error(s) during execution, please check the logs for more details.

As best I can tell, it appears that dependabot doesn't like the syntax we used to "ignore" the minor upgrades for typescript (and possibly also zonejs). These errors started only after merging the above PRs, so I think they are the cause.

So, this PR is just moving those settings to the ignore section and specifically ignoring major & minor upgrades of those dependencies. Hopefully, this will help fix things for dependabot.

Merging immediately as this is just dependabot & it's not possible to test without merging.
