Forms: Fix patterns required indicator issue (#45495)

* Fix default value issue for requiredIndicator

This revealed that WordPress was applying the deprecated block schema
(INNER_BLOCKS_DEPRECATION) instead of the current one when parsing
patterns.

When parsing a self-closing field block from a pattern WordPress mathec
it against the deprecated schema, which didn't have requiredIndicator
defined, so it was stripped out even when explicitly including it in the
pattern definition.

I've added reqwuiredIndicator to INNER_BLOCKS_DEPRECATION so the
deprecated schema recognizes it as valid.
