feat: support php-parser 3.4.0 (pipe operator and readonly anonymous classes)

[jorgsowa]

Supports php-parser 3.4.0

Changes:

• readonly anonymous classes
• pipe operator (PHP 8.5)

[czosel]

This is probably still missing the dependency bump

[jorgsowa]

Yes, missed that. Done in 6ad88c1 (this PR)

[czosel]

👍 now you might still have to set the PHP version in jsfmt.spec.js

[czosel]

Hmm, I think this still needs a few changes:

• unnecessary brackets
• pipe operator should be at beginning of each line if multi-line
• only one pipe per line

The PHP docs show an example where the trailing semicolon is on its own line, we might also want to implement that?

Suggested change

	$result =
	"Hello, World!" |>
	(strtoupper(...) |> (trim(...) |> htmlspecialchars(...)));
	$result = "Hello, World!"
	|> strtoupper(...)
	|> trim(...)
	|> htmlspecialchars(...)
	;
