add linkify custom regex to excluding parenthesis in the end of link

[makrusali]

i added some push to the website for following issue #31

this https://handmade.network/), is a valid link as i check in here https://0mg.github.io/tools/uri/
but turns out github doesn't render '),' as part of the link
so i add custom config url regex for linkify,

i remove the ( and ) from [-a-zA-Z0-9@:%_+.~#$!?&/=\(\);,'">\^{}\[\]`] and after that i add a condition or if we find ( or ) it must be followed by [-a-zA-Z0-9@:%_+~#$!?&/=;'">\^{}\[\]`] excepting , and . to make ( or ) as a part of the link, otherwise not

original regex for linkify is (default from goldmark):
from: https://github.com/yuin/goldmark/blob/master/extension/linkify.go

^(?:http|https|ftp)://[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-z]+(?::\d+)?(?:[/#?][-a-zA-Z0-9@:%_+.~#$!?&/=\(\);,'">\^{}\[\]`]*)?

and modified version is like this

^(?:http|https|ftp)://[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-z]+(?::\d+)?(?:[/#?](?:[-a-zA-Z0-9@:%_+.~#$!?&/=;,'">\^{}\[\]`]|\([-a-zA-Z0-9@:%_+~#$!?&/=;'">\^{}\[\]`]|\)[-a-zA-Z0-9@:%_+~#$!?&/=;'">\^{}\[\]`])*)?

the wasm build is error for me in hmn\src\parsing\wasm\parsingmain.go:14 undefined: parsing.ForumPreviewMarkdown so i replace it to PostPreviewMarkdown only just to test and i din't commit them.

sorry if my explanation sound confusing, i try my best to write this
