Docs: Correct `@since` tags for some block parser properties and methods.

This affects:
* `WP_Block_Parser::$empty_attrs`
* `WP_Block_Parser::next_token()`
* `WP_Block_Parser::freeform()`
* `WP_Block_Parser_Block::$innerContent`

The `@since` tags referred to early Gutenberg versions instead of WordPress core. These properties and methods were introduced in WordPress 5.0, so `5.0.0` is the correct version.

Some of the other `@since` tags are removed, as they are related to early Gutenberg development before it was merged into WordPress core, and are not relevant for core.

Follow-up to [43751], [43884], [43955] for the 5.0 branch, [44116], [44261], [44281] for trunk.

Props Chouby.
