🐛 allow svn source repos to be validated (#1346)

- Fixes customer case 03608826
"When setting up an a new application to be analysed by the MTA, we
select Subversion as the repository type and enter the URL with the SVN
protocol. The UI tells us that this is not a valid URL for a Subversion
repository. Changing the URL protocol to HTTP makes the error go away
but our department wide Subversion server is set to use only SVN
protocol and cannot be changed. This leaves us unable to scan an
application a Subversion hosted application with a valid SVN URL."

Adds regex to allow SVN repos to be validated when adding as a source
repo to applications
