isomorphism(PermGroup, ::WeylGroup) for missing irreducible types

[TWiedemann]

Adds support for all missing irreducible types (B, C, D, E, F, G) in isomorphism(PermGroup, ::WeylGroup) and also for non-canonical orderings. Reducible types are still missing.

@lgoettgens I don't know whether this should be merged already, but I think the code is mature enough for someone else to have a look.

This is a continuation of #4264, I guess.

Thanks! I have a few comments, mostly documentation-related. Once they are resolved, I would be happy to merge this PR. If you prefer to wait until reducible types are working, this would be fine for me as well.

[TWiedemann]

Thanks for your comments! I resolved everything. I plan to look into the reducible types soonish, but I see no harm in merging already.

Thanks for the adaptions! Could you please have a look into the two failing CI jobs? Both should have some instructions in the failure log. Once that's done, this is good to go from my POV.

Sure, will do that next week.

I applied JuliaFormatter and bibtool and fixed the bib entry (changed "article" to "Article"). Now it's all fine (except for the nightly test).
