[QualGroup] Update Slides Section, Add AI Transcription Policy, Clean Up

[uwendi]

This patch makes the following updates to the QualGroup.rst documentation:

✅ 1. Replace slide links with Google Drive URLs

Replaced links to slide PDFs previously hosted in llvm/docs/qual-wg/ with publicly accessible links to the same files stored on Google Drive.

✅ 2. Remove duplicated "Current Topics & Backlog" section

Removed an accidental duplication of the "Current Topics & Backlog" section to improve clarity and structure.

✅ 3. Add "AI Transcription Policy" section

Introduced a dedicated section documenting the group's practices and expectations regarding AI-based auto-transcription during sync-up meetings. Includes purpose, consent practices, retention details, and how participants can opt out or raise concerns.

✅ 4. Remove qual-wg subfolder from docs

Removed the now-unused llvm/docs/qual-wg directory after migrating slide hosting off-repo. No longer needed for qualification group documentation.

✅ 5. Revision of the introduction

Updated sentence to reflect the most current and widely relevant safety standards: adding IEC 61508 and IEC 62304 for broader applicability, and replacing EN 50128 (older standard in railways) by EN 50716 for correctness.

All the links are working and found no evident typos. LGTM

Just a general note (not related to this change specifically): In the introduction (llvm/docs/QualGroup.rst), we mention ISO 26262, DO-178C, and EN 50128. Since EN 50128 has been withdrawn and superseded by EN 50716, and given that IEC 61508 (parent standard) and IEC 62304 (medical devices) are also relevant, would it make sense to update/extend that list?

[uwendi]

Thank you very much @petbernt I revised the sentence for both correctness and broader applicability following your comment, and included it in this patch/PR.

Hi @iznogoud-zz @petbernt
Would it be possible for any of you to approve and merge this PR? Thank you very much in advance!

[iznogoud-zz]

Hi @uwendi the approve option is disabled on my end. I probably missing some permissions. Maybe @petbernt is able to approve it.

[uwendi]

Thank you for trying @iznogoud-zz !

[petbernt]

I don’t currently have approval/merge permissions in this repository, so I can’t approve or merge this PR myself.

[uwendi]

No problem @petbernt thank you so much for your reply.

@evodius96 or @petar-jovanovic, would you be so kind to help? Thanks in advance!
