`about(BigInt(0))` throws exception

[screwdog]

On Julia 1.10 an exception occurs when using About on BigInt values.

I've come across the same issue with my package LinearCombinations.jl:

julia> using About, LinearCombinations

I wasn't able to reproduce the BigInt failure, but for the LinearCombinations reproducer, I believe implementing the relevant fixes from https://github.com/JuliaLang/julia/pull/54948/files in the StyledStrings.jl compat branch would fix the issue.

Trying BigInt(1), it seems fine on the development version, and StyledStrings compat work is incoming, so I'll close this for now but do let me know if this remains unfixed :slightly_smiling_face:
