Why not fix this in AWSS3.jl?
Isn't it a super simple change?
Whereas this workaround is tech debg we have to remember to come back and remove.
I won't block this PR over it though.

It might be a simple change but I still don't know what the change should be. (I don't have enough "theory" yet of AWSS3/FilePathsBase to make the right change)

There are some rough suggestions here:

• Error for relpath on equal S3Paths rofinn/FilePathsBase.jl#156 (comment)
• CI test failure: MethodError: no method matching parse(::Type{S3Path{Nothing}}, ::S3Path{Nothing}) JuliaCloud/AWSS3.jl#227 (comment)
