Parser regression in 1.10beta1

[nilshg]

Fredrik suggested that I link this JuliaSyntax issue here for consideration on the 1.10 milestone:

JuliaLang/JuliaSyntax.jl#332

In short, using Markdown; md"""$)""" errors in JuliaSyntax but used to parse fine in the old parser (i.e. works on 1.9 and earlier).

This also affects us: oscar-system/Oscar.jl#2596

Reduced:

julia> Meta.parse(")", 1, greedy=false, raise=true)

Should give an error of course, but gives an unexpected internal error. @c42f

Just a comment: As far as I can tell, one also runs into this error when building the Julia documentation.
