ci: add bun package manager to e2e tests

alan-agius4 · alan-agius4 · commit 6a8ce23a39a1 · 2025-11-19T11:41:07.000Z
This commit introduces support for the `bun` package manager in our end-to-end tests.

The following changes are included:
- The `bun` package manager is now part of the test matrix in the CI configuration.
- The package manager flags for `bun` have been updated to align with the latest version.
- The `ng add` command has been updated to support `bun`, including a workaround for a symlink issue.
- Tests that are not compatible with `bun`, such as those for unscoped authentication, are now skipped when `bun` the active package manager.
