Cryptic error thrown when "_" included in repository name

[alex-s-gardner]

Registering my first package I got the following cryptic error thrown by AutoMerge.run:

Error: Some registries failed to update:
│     — `/tmp/jl_Mc2e8U/registries/General` — registry dirty
└ @ Pkg.Registry /buildworker/worker/package_linux64/build/usr/share/julia/stdlib/v1.7/Pkg/src/Registry/Registry.jl:450

After a bunch of searching and digging I realized that my package name was non-conforming and included an underscore ("_") in the package name.

I realize that the correct naming convention is detailed here: https://juliaregistries.github.io/RegistryCI.jl/stable/guidelines/#Automatic-merging-guidelines

But I missed the only "alphanumeric characters" in my first skim of the document

I wonder if a check could be added for basics things like conforming package names and that a [compat] list is included in the .toml file... this would make it easier for non-observant people like me to trace issues with first-time package registration... then again, maybe it's good to have a bit of a barrier to keep lazy readers like me from registering a package ;-)

All of these checks already exist, and the list of failed checks is posted in the AutoMerge comment, e.g. #57187 (comment)
