docs: fix duplicated-word typos in docs and code comments

[durvesh1992]

Summary

Fixes accidental duplicated words ("the the", "use use", "when when", "of of", etc.) across user-facing documentation and code/doc comments. These are comment- and docs-only edits with no behavior change, so they are safe and self-contained.

Notes

• Vendored / @generated files (e.g. the Bazel Remote Execution proto, testcases/parse/rust.star) and grammatically-valid repeats (e.g. "that that's the case", "and/or") were intentionally left untouched.
