* feat: add mongosh support to boundary connect mongo

* feat: add auth-source flag for MongoDB connect command

- Add -auth-source flag with default value 'admin' for root users
- Add BOUNDARY_CONNECT_MONGO_AUTH_SOURCE environment variable support
- Update documentation with new flag and correct mongosh default
- Improve MongoDB test with explicit auth-source parameter
- Fix Docker configuration formatting for better readability

This ensures MongoDB root users authenticate against the admin database
by default while allowing flexibility for custom authentication databases.

* test(e2e): Fixed false positive in Mongo connect test; use UriNetwork and container hostname

* make gen

* fix: Removed unnecessary variable containerName from the MongoDB E2E test

* feat(connect/mongo): Build URI compatible with mongosh and set default authSource

* feat(connect/mongo): use mongosh flags following PostgreSQL pattern

* remove 'connection string' from auth-source usage text

* Update internal/cmd/commands/connect/mongo.go
