MLE-24230 Second batch of package updates

- Bumped json-text-sequence to latest version (1.0.1 to 4.0.2)
- Bumped qs from 6.11 to 6.14
- Removed carets to request explicit versions

And had Copilot clean up the "overrides" section. Most of these look like they originate from devDependencies - though a lot of them may have been from eslint, which was mistakenly party of dependencies. Will see what Black Duck thinks, but npm is reporting zero vulnerabilities.
