### What changes were proposed in this pull request?
Changed the `CURRENT_TIMESTAMP` comparison in
`MysqlColumnDefaultValueConverter` from case-sensitive `startsWith` to
case-insensitive `StringUtils.startsWithIgnoreCase`.
### Why are the changes needed?
MariaDB returns default values with different casing (e.g.,
`current_timestamp` in lowercase) compared to MySQL (e.g., `CURRENT_TIMESTAMP`
in uppercase). The existing `String.startsWith()` check is case-sensitive,
which causes it to fail when connecting to a MariaDB database via the MySQL
catalog, resulting in incorrect default value parsing.
### Does this PR introduce _any_ user-facing change?
No user-facing API changes. This fix ensures MariaDB users can correctly use
the MySQL catalog with proper default value handling.
### How was this patch tested?
Manually tested by connecting the MySQL catalog to a MariaDB instance and
verifying that columns with `CURRENT_TIMESTAMP` as default value are correctly
parsed.
