[BUG] nx-serverless: Property 'port' does not match the schema. '7777' should be a 'number'.

[tstackhouse]

Describe the bug
When using serverless offline, if the port is not explicitly specified in workspace.json it will fallback to the default in libs/nx-serverless/src/builders/offline/schema.json which is "7777", not 7777, which causes the above schema failure.

To Reproduce

1. In any project using nx-serverless, do not specify port in the options for the serve command in workspace.json
2. Attempt to run nx serve
3. Command fails with schema error

Expected behavior
Serverless offline is started on the default port of 7777.
