Failure with space in filenames

[blegat]

I had a examples with a file named "Bound on Global Extremum.jl".
It worked before but with the lastest version of Literate and Documenter, it fails with

ERROR: LoadError: invalid '@example' syntax: @example Bound on Global Extremum

See https://github.com/jump-dev/SumOfSquares.jl/pull/201/checks?check_run_id=3464443765#step:5:116
Maybe Literate should replace spaced by underscores when generating the label to be used with @example so that there is no space in the name.

I don't think anything in Literate has changed here, so probably a Documenter change. Probably before the name of the example in Documenter would be just "Bound" but now seems like there is some extra restrictions.

Maybe Literate should replace spaced by underscores when generating the label to be used with @example so that there is no space in the name.

Sure, seems like a good idea.
