@scbedd can this be reviewed?

[scbedd]

Hey @lzchen these changes look good, but unfortunately what will happen is on the very next release, your changes will be wiped out!

The readme file you changed in this repo is auto-populated from this readme file when we release a new version of the azure-monitor-opentelemetry-exporter package.

I will gladly sign off this review after you merge a PR to the repo w/ these same changes.

@scbedd

Thanks for the headsup. I am already making the same changes in that README file in this [pr](Azure/azure-sdk-for-python#34462. If this doc is indeed populated from that README file then I can close this PR.
