metavariable-pattern not flagging with PHP code

[colleend]

Describe the bug
Metavariable-pattern is flagging PHP code with 'generic' mode, but not with 'php' mode.

To Reproduce
For instance, this doesn't flag: https://semgrep.dev/s/WRD2

But this does: https://semgrep.dev/s/02Wj

Expected behavior
Would expect it to flag with php as the language.
