fix: Formatting\ReturnTypeSniff to use new type of token for parenthesis

[michalbundyra]

Since PHP_CodeSniffer 3.10.0 parenthesis token has been changed to:

• T_TYPE_OPEN_PARENTHESIS (from T_OPEN_PARENTHESIS)
• T_TYPE_CLOSE_PARENTHESIS (from T_CLOSE_PARENTHESIS)

and therefore the sniff did not work correctly for composite return type declarations.

Bump minimum PHP_CodeSniffer version to 3.10.3 so the new tokens are defined.
