refactor: Update the lists of files included in packages

[mondoreale]

This pull request updates the packaging configuration for several packages, focusing on standardizing the files field in package.json and cleaning up ignored files. The main goal is to ensure that only the necessary files are included in published npm packages, improving consistency and reducing package size.

Changes

Packaging and file inclusion improvements:

• Standardized the files field in package.json across multiple packages to consistently include dist, exclude *.tsbuildinfo, and selectively include or remove README.md and LICENSE files. (packages/autocertifier-client/package.json [1] packages/autocertifier-server/package.json [2] packages/test-utils/package.json [3] packages/trackerless-network/package.json [4] packages/browser-test-runner/package.json [5]
• Added a files field to packages/browser-test-runner/package.json to ensure only the necessary files are published.
• Remove .npmignore in packages/autocertifier-client – the files field now controls published content.¹

Footnotes

1. autocertifier-client was the only package with .npmignore. It also had files in its package.json. Now it's just like all the other packages – driven by the files field *only*. ↩

Mostly clean-up, and mostly about autocertifier-client where the redundant .npmignore is removed.

I've double-checked the lists of packed files with npm pack --dry-run. FYI.

Merging in.
