Summary

Fixes two seperate / seperated typos in the documentation:

• packages/gcp-sphinx-docfx-yaml/docs/How_to_Document_Python_API.md
  • "inline link and seperate link" → "inline link and separate link"
  • the RST example anchor is now consistently spelled: .. _Separated Link: / \Separated Link`_(and the example URL hosthttp://separated.external.link`)
• packages/google-cloud-spanner/docs/opentelemetry-tracing.rst
  • "# in a seperate thread to not block on the main thread" → "# in a separate thread to not block on the main thread"

Both files are documentation only — no library code paths are touched, so there is no behavior change and no test impact.

Why

The RST guidance page is the reference that library authors copy from when writing docstrings, so the misspelled anchor name in the example is what people end up copying. The Spanner tracing page has the same typo in the code sample that readers copy-paste into their own projects.

Note: the anchor rename is applied to both halves of the RST reference (the reference text \Separated Link`_and the target definition.. _Separated Link:`), so the example remains internally consistent and still demonstrates the same "separated link will fail" behavior the page is documenting.

Code Review

This pull request corrects spelling mistakes in the documentation files, specifically fixing occurrences of 'seperate' and 'seperated' to 'separate' and 'separated' in How_to_Document_Python_API.md and opentelemetry-tracing.rst. There are no review comments, so I have no feedback to provide.
