feat: add empty array integrations field to the manifest upon write-manifest

[joshyam-k]

Intent

Add empty array "integrations" field to the manifest upon write-manifest. This is part of the work around auto-associating integrations with content upon deployment. See the main ticket for more information.

Fixes: #32761

Type of Change

• Bug Fix
• New Feature
• Breaking Change

Approach

• adds a TypedDict for the ManifestIntegrationRequests type
• added empty integrations field into make_source_manifest
  • had to manually edit create_voila_manifest as it is the only one that doesn't call make_source_manifest internally.

Automated Tests

• added new unit tests for each write_*_manifest_json function
• updated existing unit tests that called make_source_manifest

make test passes
