feat(php): add support for php

add php support

[HiPhish]

Can you please add a little PHP test file to test/highlight/php? It does not need to make sense (although it would be nice if it would compile), but it should contain an example for each of the patterns you have defined. Ideally with some levels of nesting so I can see the effect immediately.

[HiPhish]

Perfect, thank you.

sorry for bumping this pr after merge (is it worth creating new issue?). i found bad behavior in uncapsed_string

may it be the same issue as https://github.com/HiPhish/rainbow-delimiters.nvim/pull/22#issuecomment-1671395930

Probably. You can press a in the TS Playground to toggle the display of anonymous nodes. There you will see that all { and } are on the same level of ecapsed_string.
