8776694a33 Use numeric font weights instead of keywords.
When Open Sans was in use, the `300`, `400`, and `600` weights were loaded. `400` is the equivalent of `normal`; however, `bold` is equivalent to `700`, not `600`. With the move to system fonts, we need to be specific rather than relying on the lack of a `700` weight. Not all system fonts include a `600` weight; in those instances, they will use the `bold`/`700` weight.

The WordPress CSS Coding Standards have been updated accordingly.

d242446e59 Multisite: Use WP_Site_Query to power WP_MS_Sites_List_Table.
`WP_Site_Query` provides for a cleaner `prepare_items()` method. It significantly improves the search experience in the sites list table:

* In a subdomain configuration, domain and path are searched for a provided terms.
* In a subdirectory configuration, path is searched for a provided term.
* The full domain is searched in a subdomain configuration rather than the portion not matching the network's domain.
* Terms are searched as `%term%` by default. Adding `*` in the middle of a term will search `%te%rm%`.

6b7f68855b Accessibility: Remove the ARIA roles from the wp.a11y.speak() live regions.
When Firefox repaints some elements, NVDA may announce "alert" even when there's
no actual message dispatched to the live region. The NVDA implementation differs
from other screen readers and is currently under discussion. To avoid a subpar
user experience better to remove the roles since they're basically redundant.

b8b7a00889 HTTP API: Update Requests.
This introduces a minimum value of 1 second for timeouts passed to cURL.

Internally, cURL uses alarm() for interrupts, which accepts a second-resolution timeout. Any values lower than 1 second are instantly failed rather than being rounded upwards. While this makes the experience worse for those using asynchronous DNS lookups, there's no way to detect which DNS resolver is being used from PHP.

486961626c Query: Allow plugins to supply post results instead of having WP_Query fetch them from the database.
Returning a non-null value from the new `posts_pre_query` filter will cause
`WP_Query` to skip its database query, so that posts data can be provided from
elsewhere. This is useful in cases where post data may be mirrored in a
separate location, such as an external search application.

Developers should note that the `WP_Query` properties generally used to
calculate pagination - specifically, `found_posts` and `max_num_pages`, which
are determined by default in `set_found_posts()` - must be provided explicitly
when using the `posts_pre_query` filter; since `WP_Query` will not be
contacting the database, it will have no access to `SELECT FOUND_ROWS()`.
The `WP_Query` instance is passed to `posts_pre_query` by reference, so that
these properties can be set manually if needed.

50ab6e8df0 Docs: Improve first-order clause documentation for the $meta_query parameter in the constructor for WP_Meta_Query.
First-order meta query clauses are defined as clauses that have either a 'key' or 'value' array key. When using named first-order clauses in meta queries to order results in the parent query, `WP_Meta_Query` can additionally accept first-order clauses at the sub-clause level, which was not previous documented.

Fixes #32659.
