Correct @SInCE version for block parser package (#24819)

Fixes #22050

The @SInCE values in packages/block-serialization-default-parser/parser.php (converted to class-wp-block-parser.php in WordPress core) were all set to the version of Gutenberg that they were introduced in, rather than the version of WordPress they were introduced in.

In this patch those version values are properly set to 5.0.0 - the version of WordPress in which they were introduced.

Props: @JustinyAhin
