Cloudflare Pages build and branch configuration error for pull requests

[jbampton]

Next PR shows deployments are working but site is 404 for PR deployment previews:

#999

Working of the main branch deploys:

Configured now and working for 3 different branch cases with branch control and production and preview environments.

• gh-pages
• main
• any branch from org users that have write access

Fixed the server build by skipping automatic dependency install by setting the build variable:

SKIP_DEPENDENCY_INSTALL=1

This skipped installing the non related Python packages.

A few other settings:

Build command:npm ci && npm run build
Build output:_deploy
Root directory:
Build comments:Enabled
