 Code Modernization: Replace `isset()` with null coalescing in
 `WP_Roles::get_role()`.

 Since PHP 7.0 introduced the [https://www.php.net/manual/en/migration70
 .new-features.php#migration70.new-features.null-coalesce-op null
 coalescing operator], and WordPress now requires at least PHP 7.2.24,
 `isset( $var ) ? $var : null` ternary checks can be safely replaced with
 the more concise `$var ?? null` syntax.

 As some new code using the null coalescing operator has already been
 introduced into core in recent releases, this commit continues with the
 code modernization by implementing incremental changes for easier review.

 Follow-up to [2703], [61403].

 Props dilipbheda, mukesh27, spacedmonkey, SergeyBiryukov.
 Fixes #63216. See #58874.
