Update performance.md (#948) 
We haven't updated this document in a while and yet there was a fair
amount of performance work, some of which can be documented here.

Note that this is not fully comprehensive in that it excludes a lot of
internal tuning that is difficult to describe other than with "we made
things faster".

Update lint.md to specify language on fenced code blocks which have none (#946)

they were inconsistent with the others on the same page.

Fix grammar issues (#915) 
- The type list for function declarations does not accept defaults, but
the grammar incorrectly allowed this.
- Allow the empty table type `{}`
- Allow composite types and types surrounded by parentheses (e.g.
`string??`, `(string)`, `(string | number) & boolean`)

News about string interpolation feature and a syntax page update (#829) 
News can be viewed
[here](https://vegorov-rbx.github.io/luau/2023/02/02/luau-string-interpolation.html)
And syntax can be viewed
[here](https://vegorov-rbx.github.io/luau/syntax#string-interpolation)

Note that link appears to be broken in the news section. It goes to
`https://vegorov-rbx.github.io/syntax#string-interpolation` instead of
`https://vegorov-rbx.github.io/luau/syntax#string-interpolation`
The link I use in the source is `/syntax#string-interpolation` but the
root 'offset' is different on Luau website (doesn't have extra 'luau'
folder) and on my GitHub pages.
Hope this is ok. But if GitHub page masters know how to avoid this,
please let me know.

Improve description of bit32.extract/replace. (#585) 
Fix description incorrectly saying that parameter w specifies an upper range. w is actually a width. Proof:

    print(bit32.extract(2^32-1, 3, 4)) -- prints 15, not 1.

Also indicate that the position is 0-based, and that the function will error if the selected range exceeds the allowed bounds.

Add documentation on singleton types and tagged unions to typecheck.md. (#440) 
Update the typecheck.md page to talk about singleton types and their uses, tagged unions.

As a driveby, improve the documentation on type refinements. And delete the unknown symbols part, this is really dated.

* Update docs/_pages/typecheck.md to fix a typo
