Description

According to the test page invitation for WP 6.3, a time to read block will be available in this version of WP. But I cannot find it among the block list nor fail to invoke it via the "/" command. Whereas the block is available in GB 16.1 which is slated to be included in WP 6.3.

Step-by-step reproduction instructions

1. Open a template or a page
2. Search for block name "time to read"
3. Observe there is no block with that name
