Make comments non-blocking by default

[goerz]

I appreciate the community review of the General registry, in that anyone can leave a blocking comment on a new registration. However, the more "community review" actually happens, and thus, the more comments there are for registration PRs, the more it is a problem that comments are blocking by default.

I would propose that we change from comments being blocking unless they contain [noblock] to comments being non-blocking unless they contain [block]. I have no problem personally navigating [noblock], but I have to spend a very significant percentage of my registry review time just typing messages to people reminding them to add [noblock]. Latest example:

#117882

It's very easy to forget about [noblock] once a discussion gets going. My experience is also that 90% of comments are intended to be non-blocking. Those that are intended to block are usually just the first comment, and usually by a small group of people (myself included) that check new submissions for issues such as misleading names or insufficient documentation. I think that group of people will easily adapt to [block].

P.S.: I'm not sure if this issue belongs here, or, e.g., in https://github.com/JuliaRegistries/RegistryCI.jl. Please feel free to transfer if appropriate.

I think that makes sense. One thing that might make this easier is a new label: JuliaRegistries/RegistryCI.jl#573

However that can work in addition to changing the default.

For now, let's try keeping the default as blocking, and see if JuliaRegistries/RegistryCI.jl#573 makes things easier.
