fix(requirements): pin lxml and xmlsec on sumac to fix pylint CI

[kingoftech-v01]

Withdrawn by author.

I submitted 36 pull requests in a short window and mass-tagged the maintenance working group. That was the wrong way to approach this repository. I apologise to @kdmccormick and to the @openedx/wg-maintenance-openedx-platform members for the notification noise.

For the security-related patches, I should have used the private disclosure channel at security@openedx.org rather than public pull requests. The original body of this PR included exploit paths and affected line numbers; that content has been removed here to avoid indexing. Any legitimate security finding will be re-reported privately through the proper channel.

For the bug-fix patches, I plan to re-engage the community through the correct process: discussing on https://discuss.openedx.org first, then submitting one focused change per PR, and only tagging maintainers when a PR has passed CI and an individual reviewer asks to be involved.

No further action requested on this PR.

CLA signed via DocuSign. Re-triggering the check.

Other checklist items:

• Product approval: not required — bug/security fix, no new feature or product surface change.
• Context: full intent analysis, fix scope, test plan, and refs are in the PR description.
• Green build: will run once the CLA gate unblocks CI.
