Type constraint link to removed php function and is not used in symfony

[alamirault]

On this page https://symfony.com/doc/current/reference/constraints/Type.html#type, we have a link to some php is_* functions.

symfony-docs/reference/constraints/Type.rst

Lines 172 to 187 in 95d5763

	* :phpfunction:`array <is_array>`
	* :phpfunction:`bool <is_bool>`
	* :phpfunction:`callable <is_callable>`
	* :phpfunction:`float <is_float>`
	* :phpfunction:`double <is_double>`
	* :phpfunction:`int <is_int>`
	* :phpfunction:`integer <is_integer>`
	* :phpfunction:`iterable <is_iterable>`
	* :phpfunction:`long <is_long>`
	* :phpfunction:`null <is_null>`
	* :phpfunction:`numeric <is_numeric>`
	* :phpfunction:`object <is_object>`
	* :phpfunction:`real <is_real>`
	* :phpfunction:`resource <is_resource>`
	* :phpfunction:`scalar <is_scalar>`
	* :phpfunction:`string <is_string>`

is_real is deprecated since php 8.0.

And Type Validator does not use this function (same for is_double)

https://github.com/symfony/symfony/blob/ed96673e64ebaca3f47012c230823dcddd59a2ba/src/Symfony/Component/Validator/Constraints/TypeValidator.php#L24-L41

WDYT to update doc, and for each type, precise real php function used.

Maybe something like this ? (I don't know if it's a valid syntax for SymfonyDocsBuilder)

:phpfunction:`float, double, real <is_float>`

[MrYamous]

:phpfunction:`float, double, real <is_float>`

This is valid syntax yes, but what do you think about keeping one type per list item ?

is_real is deprecated since php 8.0.

Actually it was removed, according to this link.
