These should be aligned. This was because I misread the bison docs originally. Some folks are hitting this when trying to render Rails views too deeply.

[ruby/prism] Increase value of PRISM_DEPTH_MAXIMUM to 10000

The previous value of 1_000 was added with a reference to the Bison
parser¹, but the value of YYMAXDEPTH in the Bison docs is 10_000,
not 1_000.

Fixes [Bug #21044]
