[doctest] StackOverflowError in docstring involving `DocStringExtensions.TypedMethodSignatures` in Julia v1.11

[giordano]

With Breeze@d51d279ba7dae0a768aafad593e79dd4d4117e65 and Julia v1.11.9 (note: only with this version of Julia) we often (but not always!) get on CI the following error in doctests:

│ ┌ Error: parsedoc failed to parse a docstring into Markdown. This indicates a problem with the docstring.
│ │   exception = StackOverflowError:
│ │   docstr.data =
│ │    Dict{Symbol, Any} with 5 entries:
│ │      :typesig => NTuple{5, Any}
│ │      :module => Breeze.ParcelModels

This points to https://github.com/NumericalEarth/Breeze.jl/blob/d51d279ba7dae0a768aafad593e79dd4d4117e65/src/ParcelModels/parcel_dynamics.jl#L378-L383. I haven't been able to reproduce this error when running the doctests locally with Julia v1.11.9, I have no clue of where the error comes from, nor of what it could possibly mean.
