SPIRV.jl doc doesn't render the ANSI escape sequences

[minecraft2048]

For example this: https://serenity4.github.io/SPIRV.jl/dev/api/#SPIRV.@fragment-Tuple

On my browser (Firefox) it shows a bunch of ANSI gibberish instead of colored text:

which makes it hard to see

Indeed, I looked into it a while ago but there is AFAIK no way that we can have arbitrary colors in docstrings from the REPL besides the usual Markdown syntax highlighting, unless we use ANSI sequences which unfortunately don't print well in the browser. The trade-off of having colors in the REPL for less readable online docs seemed to be decent to me, at some point we could revisit that and perhaps strip ANSI codes from the generated documentation but that seems to require a nontrivial amount of effort (I can review if someone wants to do it).
