docs: add hw specific cert tables

[amd-aliem]

Add hardware-specific cert tables. Github issues are now parsed for the proc-XXXX label, which contains the processor series number that the tests were run on (7003, 9004, etc). The corresponding table in docs/certification.md is updated. If the issue's milestone matches the native processor series (i.e. milestone 3.0 for milan 7003), the main README.md table is updated as well.

Additional changes:

• Fix concurrency issue to handle multiple issues at the same time gracefully. Concurrency setting only allows 2 max, so remove and allow jobs to handle retrying in case of conflicts.
• Enforce creating a new matrix table branch when a new PR is opened by the github action bot. This prevents rebase issues.
• Fix automated commit message to adhere to conventional commit
• New rows will be inserted in alphabetical order

Example output after creating 6 simulated issues and merging the created workflow bot PR:

README.md - UPDATE: newly formatted README matrix (updated column names + alphabetized)
docs/certification.md

Future:

• Flesh out Certification Level Definitions Section
• Need a place with "latest" implemented certification level for each proc series to make use of the ❌ Not Certified and ⚠️backwards compatibility warnings.
