…air screen.

The table is no longer created by core as of WordPress 3.0, and support for global terms was removed in WordPress 6.1, so `$wpdb->sitecategories` is unset by default.

This commit resolves a "passing null to non-nullable" deprecation notice on PHP 8.1:
{{{
Deprecated: addcslashes(): Passing null to parameter #1 ($string) of type string is deprecated in wp-includes/class-wpdb.php on line 1804
}}}

The `tables_to_repair` filter is available for plugins to readd the table or include any additional tables to repair.

…om next_posts().

The `esc_url()` function expects to a string for `$url` parameter. There is no input validation within that function. The function contains a `ltrim()` which also expects a string. Passing `null` to this parameter results in `Deprecated: ltrim(): Passing null to parameter #1 ($string) of type string is deprecated` notice on PHP 8.1+.

Tracing the stack back, a `null` is being passed to it within `next_posts()` when `get_next_posts_page_link()` returns `null` (it can return a string or `null`).

On PHP 7.0 to PHP 8.x, an empty string is returned from `esc_url()` when `null` is passed to it. The change in this changeset avoids the deprecation notice by not invoking `esc_url()` when `get_next_posts_page_link()` returns `null` and instead sets the `$output` to an empty string, thus maintain the same behavior as before (minus the deprecation notice).

Adds a test to validate an empty string is returned and the absence of the deprecation (when running on PHP 8.1+).

…Info screen.

This resolves a fatal error if `strict_types` PHP setting is enabled:
{{{
Argument #1 ($num) must be of type float, string given
}}}

Since the goal of the Site Health Info screen is to display raw values where possible, the `number_format()` call here does not seem to provide any benefit.
