Project config should alphabetize entries.

Description

Project config diffs can get unwieldy and ugly pretty quickly. In an enterprise environment where multiple developers are contributing to a Craft project, this can create some very ugly and misleading diffs of the project.yaml file. Alphabetizing entries would help mitigate this.

We used to sort everything in the project config, but that led to a couple issues such as #3997, so then we switched to only sorting top-level items.

As of the next release, we will also start sorting any arrays when all of the nested keys are UIDs, which seems safe.

To add to @ryanpcmcquen 's description of the unwieldy diffs, this can also cause merge errors-- if two sections that contain mostly the same stuff are moved around, Git's merger can tend to really munge them up since it's not data-structure-aware.

@brandonkelly With that issue you referenced, some of Craft's resources have keys like sortorder, right? Would it solve this to extend that approach to all (or more) things?

[brandonkelly]

@tprobinson Yes, but the issue is that it was a breaking change for plugins as well. We’ll probably go back to sorting all indexed arrays by keys again in Craft 4. In the meantime I suspect that 1e808dc is going to go a long way in helping.
