Add a dynamic hook to filter the pre-rendered content of a single block.

[gigitux]

Introducing a dynamic hook, pre_render_block_{$block_name}, as a complement to the already valuable pre_render_block hook could increase the developer experience. This new hook aims to filter the pre-rendered content for a specific block, eliminating the need for conditional statements within the pre_render_block filter callback. I searched on GitHub, and many folks use the pre_render_block and add a check to ensure the logic runs only for a specific block.

Some examples:

• ​https://github.com/WordPress/wordcamp.org/blob/7823c7aa3c076f37e99a9ba8f66050ed569b94e4/public_html/wp-content/mu-plugins/blocks/source/variations/sessions-list/controller.php#L19
• ​https://github.com/buddypress/buddypress/blob/1f5ff3be1880a59a8644b00f03aeb1cd1cdd5b74/src/bp-core/bp-core-filters.php#L108

For the same reason, the render_block_{$block_name} hook has been implemented: https://core.trac.wordpress.org/ticket/46187.

I'm happy to work on it!
