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".

Fix website demo's string highlighting behaviour (#942)
Fixes #935:
* String literals that include `\z` escape sequence followed by newline
characters are now correctly highlighted.
* Unescaped backslash (`\`) character at the end of the line no longer
acts like the `\z` escape sequence inside string literals when
highlighting.

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.

Update title and fix a dead link. (#659)
Originally it was titled "Luau Recap: August 2022" but it got renamed to "Luau Recap: July & August 2022" and we just didn't fix the link here too. Also backports the title change to here too for consistency.

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.
