FTP Credentials Modal should have a 'button-primary' class on the 'Proceed' button

[mapk]

When reviewing another ticket's screenshots (#32194), I noticed that the 'Proceed' button in the FTP Credentials modal doesn't have the 'button-primary' class on it.

Existing view:

Proposed view with 'button-primary' class

To trigger this modal, follow these steps below.

1) Add this to your wp-config.php: define( 'FS_METHOD', 'ftpext' );
2) Install an old version of a plugin
3) Browse to wp-admin/plugins.php
4) Click on the update now link in the plugin’s table row

In 58149:

Administration: Add primary class to the FTP credentials modal submit button.

This helps differentiate the two buttons available in the FTP credentials modal by setting a primary class to the submit button.

Props mapk, curdin, audrasjb, shailu25.
Fixes #37647.
