Imapsync webserver and Debian 12

[CyberCr33p]

I encountered a problem with webserver after upgrading from Debian 10 to Debian 12, where a "Content-type: text/html" message unexpectedly appeared in the top left corner of the webpage.

This issue persisted even with a clean installation of Debian 12 but was not present in Debian 10.

The problem was resolved by removing the line $self->send_status( '200', 'OK' ) ; from the webserver file.

I think I encountered the same issue some time ago when I worked again on the script webserver.
I fixed the issue and made it usable in the imapsync Docker image
I renamed it from webserver to servimapsync
