Migrate all community google docs to the OpenTelemetry.io Google Workspace

[trask]

Currently community google docs are split between the (older) cncf-opentelemetry-governance@lists.cncf.io Google Account and the (newer) OpenTelemetry.io Google Workspace.

This has caused confusion on multiple occasions, and it would be nice to only have community docs in one place (the OpenTelemetry.io Google Workspace).

I wrote (or rather guided copilot to write) an automation for this and tested it with the Sampling SIG doc (which was causing problems this week because it was owned by yet another account).

It copies the doc into the OpenTelemetry.io Google Workspace, and then posts a redirect alert to the old doc:

(and then updates the link in this repo's sigs.yml/README.md)

To the extent that we can, could we make the original doc read-only/comment-only?

I was thinking to go with @andrzej-stencel's suggestion to delete the content in the original doc: #3183 (review)

That also works!

Notes:

• do both (delete the original content + make the doc read-only)
• update link in meeting invites
