"Add Version" Create Button Should Be Inactive Until Version Provided

[msymons]

Current Behavior

In the Frontend, a new project version can be created via View Details -> Add Version

The resulting dialog has a create button that is active. Clicking it without providing a Version string will result in an HTTP 400 error and some 190 lines of exception logging in the server log, starting with...

2024-09-15 19:08:46,561 ERROR [ServerRuntime$Responder] An I/O error has occurred while writing a response message entity to the container output stream.
org.glassfish.jersey.server.internal.process.MappableException: org.eclipse.jetty.io.EofException

	at org.glassfish.jersey.server.ServerRuntime$Responder.writeResponse(ServerRuntime.java:649)

If an admin is looking at the logs then they have absolutely no context for what caused the exception.

Proposed Behavior

The "Create" button should be inactive until something has been provided in the "Version" field.
