Add CKEditor support to the email body textarea

The patch contains another fix #3314082

Also, the schema was incorrect. I created a cleaned up version. Also supporting the transition of existing text only templates.

Retitling. If we can get WYSIWYG support here, that'd be awesome.

After this patch I'm getting the below error when an email is sent with commerce_email on a status change for example;

Error: Call to a member function fromArray() on null in Drupal\symfony_mailer\MailManagerReplacement->mail() (line 89 of modules/contrib/symfony_mailer/src/MailManagerReplacement.php).

Using commerce_email v1.1

I've tested the patch from #3 with v8.x-1.1 on Drupal 10.1.2 and can confirm it works well with the Symfony mailer. The formatted text set in the email configs is seen in the email received.

I have updated the patch based on Ryan's suggestion to check if the site is setup for HTML email. I have added a check for symfony_mailer, as this is the suggested module to use for HTML emails (swiftmailer has been unsupported since November 2021)
I have also included all text formats, so the user has a choice.

I saw no other config available to check if a site is setup to use HTML email, as Core MailManager only returns the default `php_mail` interface.

I don't really want to stick with modules that support HTML email (symfony_mailer or whatever), but give users the choice to figure this out themselves. Also, we probably need to add a good description for the Body field.

Committed!

Automatically closed - issue fixed for 2 weeks with no activity.

Can this be the cause of issue with missing BODY field in translations? Only label and subject
