Remove onnxruntime team from CODEOWNERS

[garymm]

There are currently 98 members in the team. Requesting review from
all of them for every PR is too noisy. Individuals can subscribe to the
repo if they want to receive notifications for every PR.

@garymm - will github still require a review before merging PRs if the files included in the PRs don't match the whitelisted paths mentioned in the CODEOWNERS file? If not, we can't remove the onnxruntime line.
Like other repos, we've the following configured for the master branch.

Follow up question.

I believe you can configure GH to require reviews for all PRs by selecting "Require pull request reviews before merging" in "Branch protection rules".

@pranavsharma I'll wait for your approval before merging this.
