Changes proposed in this Pull Request:

During the last release to WordPress.org, two issues were encountered. Those were fixed directly in the codebase that gets deployed to WordPress.org so bringing those changes over to this repo:

1. Ensure we have a proper plugin name in the readme.txt file. This has been set for 9+ years so not sure why it's causing an issue now but it's a good thing to fix anyway
2. Remove woocommerce-bookings from the list of Required Plugins. Bookings is required but because Bookings isn't hosted on WordPress.org, it's been noted that this can cause problems (see https://make.wordpress.org/core/2024/03/05/introducing-plugin-dependencies-in-wordpress-6-5/)

Nothing really needed to test here
