Fix php-compatibility constrains

[rsanzante]

Description copied from dlopez-akalam#1

Recently, in the develop branch of phpcompatibility/php-compatibility has been removed the support for squizlabs/php_codesniffer v3.x in favor of v4.x. PHPCompatibility/PHPCompatibility@93ef2b8

That is incompatible with metadrop/grumphp-php-compatibility, and also incompatible with drupal/coder. However, the release 10.0.0-alpha2 of phpcompatibility/php-compatibility still declares the compatibility with squizlabs/php_codesniffer 3.x.
Considering the date of this commit 516059d and comparing it with the releases of https://github.com/PHPCompatibility/PHPCompatibility/tags I'm changing the constraint so metadrop/grumphp-php-compatibility can continue being installed

The version constraint syntax is invalid. In Composer, multiple version constraints must be separated by a comma (,) for AND logic. The current syntax >9.3.5 <10.0.0-alpha3 will cause a parsing error.

Should be: ">9.3.5,<10.0.0-alpha3" (note the comma and quotes)

Alternatively, you could use the more common caret operator: "^9.3.5" which means >=9.3.5 <10.0.0

Suggested change

	"phpcompatibility/php-compatibility": ">9.3.5 <10.0.0-alpha3",
	"phpcompatibility/php-compatibility": ">9.3.5,<10.0.0-alpha3",

From composer docs:
"You can define multiple ranges. Ranges separated by a space ( ) or comma (,) will be treated as a logical AND. A double pipe (||) will be treated as a logical OR. AND has higher precedence than OR."

Bold text added by me.
