Code Review

This pull request updates the CHANGELOG.md to document a Firebase Data Connect local toolkit update to v3.3.4 and a fix for Angular SDK generation. However, the actual code changes for the version bump are missing from the PR, and the PR description does not follow the repository's required format. Feedback also includes a suggestion to remove redundant phrasing in the changelog and a request to verify if related command logic needs to be updated for the new SDK target.

The pull request title and this changelog entry indicate an update to the Firebase Data Connect local toolkit to v3.3.4, but the actual code changes (e.g., version bump in package.json or a version constant file) are missing from this PR.

Additionally, the PR description is empty, which violates the repository style guide requiring ### Description, ### Scenarios Tested, and ### Sample Commands.

The phrasing [fixed] Fixed is redundant and inconsistent with the existing changelog entries. Furthermore, if this update introduces a new angularSdk target, please verify if src/commands/dataconnect-sdk-generate.ts needs to be updated to include it in the loadAllWithSDKs filter, as it currently only checks for other SDK types.

Suggested change

	- [fixed] Fixed an issue where Angular SDK generation would fail.
