Expand CODEOWNERS to each learn section owner/advocate

Broken out of #7197
Might be related to #7198

CODEOWNERS improvements associated to teams related to the APIs highlighted in the learn content

• Prerequisite Map and add frontmatter on learn pages tying to core apis #7294

for each identified api module / team:

• add a team, or expand access to write access if missing (CODEOWNERS must have write access)
• add the team and content paths to CODEOWNERS

[bmuenzenmeyer]

@AugustinMauroy identified these already

test-runner should be under the test-runner team
typescript should be under typescript team

[AugustinMauroy]

Note that we can only take action on this when we have clearly defined the learning path/graph and each subsection is associated with one or two teams max.

I've added it to the agenda to get their opinion on the matter.

No problem with adding @nodejs/typescript as codeowner of the typescript related content for review

[AugustinMauroy]

ping @nodejs/test_runner to move forward on this issue

Hey @AugustinMauroy, no problem for me regarding @nodejs/test_runner.
I'd suggest collecting some thoughts from @cjihrig, @MoLow, @atlowChemi, and @jakecastelli as well.

I'm happy to do, although I'm not as active an implementer as Chemi, Colin, and Moshe.
