{{{
#!CommitTicketReference repository="" revision="61001"
Upgrade/Install: Indicate use of `MyISAM` storage engine in upgrade check.
In MySQL 5.5.5, the default storage engine was changed from `MyISAM` to
`InnoDB`. While still available, usage of `MyISAM` has been discouraged
since and is considered legacy due to the lack of support for more modern
feature.
The percentage of WordPress sites with `MyISAM` tables in the wild is
currently unknown. This change adds a field to upgrade checks that
includes a list of tables using `MyISAM` to help make more informed
decisions about database features in the future.

Fixes #63640.
