chore: Fix spelling in src

[jsoref]

This PR corrects misspellings identified by the check-spelling action

Note: while I use tooling to identify errors, the tooling doesn't actually provide the corrections, I'm picking them on my own. I'm a human, and I may make mistakes.

Testing Plan

The misspellings have been reported at https://github.com/jsoref/adk-python/actions/runs/19056081305/attempts/1#summary-54426435973

Code Review

This pull request introduces a large number of spelling and minor grammatical corrections across various files, including documentation, source code comments, and test files. The changes are consistent with the PR's goal of fixing misspellings. I've reviewed the modifications, and they are all correct and improve the overall readability and professionalism of the codebase. I have one minor suggestion regarding a duplicated entry in the changelog, but otherwise, the PR is in excellent shape and ready to be merged.

It's a good contribution but too huge to review.

Let's fix folder by folder. Maybe starting with contributing and tests which are safer. Then go with src etc.
