chore: 2U identity cleanup and remove openedx community workflows

[rgopalrao-sonata-png]

Summary

Part of ENT-12194 (sync edx/2u-enterprise-data with openedx/edx-enterprise-data). Its pure identity/cleanup, no upstream code — opened first and independently so the sync PRs that follow aren't carrying unrelated changes.

• Fixes stale openedx/edx-enterprise-data references in catalog-info.yaml (component name), README.md (pip install path), and .github/pull_request_template.md (version/changelog/release/PyPI links, dead Travis CI reference)
• Adds an explicit 2U-ownership note to the top of README.md
• Removes 4 GHA workflows that only make sense for openedx community-contribution management, now that this repo is 2U-only: commitlint.yml, self-assign-issue.yml, add-remove-label-on-comment.yml, add-depr-ticket-to-depr-board.yml

Not included: removing the openedx-webhooks/openedx-pr-watcher-notify GitHub webhooks — that's a repo Settings change, not a code change, and needs separate explicit sign-off.

Test plan

• No functional code touched (docs/CI-config only)
• Confirm ci.yml and pypi-publish.yml still trigger normally with the 4 workflows removed

.github/pull_request_template.md:23

• The template mixes PyPi and PyPI. The canonical spelling is PyPI, and using consistent casing improves clarity (and matches the linked site name).

- [ ] After the [PyPi publish workflow](https://github.com/edx/2u-enterprise-data/actions/workflows/pypi-publish.yml) finishes, verify the version has been pushed to [PyPI](https://pypi.org/project/2u-enterprise-data/)
- [ ] PR created in [edx-analytics-data-api](https://github.com/openedx/edx-analytics-data-api) to upgrade dependencies (including 2u-enterprise-data)
    - This **must** be done after the version is visible in PyPi as `make upgrade` in edx-analytics-data-api will look for the latest version in PyPi.
    - Note: the 2u-enterprise-data constraint in edx-analytics-data-api **must** also be bumped to the latest version in PyPi.

.github/pull_request_template.md:14

• PR description says 4 community workflows were removed, including commitlint.yml, but .github/workflows/commitlint.yml is still present and still references openedx/.github reusable workflows. Either remove that workflow as well (to match the stated intent) or update the PR description so expectations match what’s actually changing.

    - This should be run from either a venv with all the edx-analytics-data-api requirements installed or if you checked out 2u-enterprise-data into the src directory used by edx-analytics-data-api, you can run this command through an edx-analytics-data-api shell.
        - It would be `./manage.py makemigrations` in the shell.
- [ ] [Version](https://github.com/edx/2u-enterprise-data/blob/master/enterprise_data/__init__.py) bumped
- [ ] [Changelog](https://github.com/edx/2u-enterprise-data/blob/master/CHANGELOG.rst) record added
