Add isTSTypeAliasDeclaration in extractSymbol

[SuperSodaSea]

Should fix [DocParser]: Failed to parse doc for (@Unnamed) caused by /** ... */ type Foo = {}.

This does fix the warning but not the spirit of the issue :D. I'll check this out tonight and make it also parse the type definition properties

[SuperSodaSea]

@ShukantPal I'll wait patiently :)

Added the data type to the TypeDef document signatures (with formatting!)

@ShukantPal I tried to bump @webdoc/cli to 2.2.0 in pixi.js and got errors like this:

Seems to be code here: https://github.com/pixijs/pixijs/blob/3ba43e50030641e2cb028c7c265e80ce0fdf6fff/packages/utils/src/url.ts#L66-L80

I added parsing for namee method signatures but not call signatures - this would be a new PR :D

[SuperSodaSea]

Just in case, don't forget about the ArrayPattern :)

[ShukantPal]

@SuperSodaSea haven't forgotten about this. Prolly need a couple weeks to finish that part
