reduce npm dependency exposure

[jgresham]

Feature details

We have some low-effort npm dependencies that we can simply copy source code from their single index.js file and include it under our src/ and npm remove the dependency. Additionally, these deps are not changing or updating frequently.

• Put the dependency in a single file
• Verify that the license of the dependency allows for this
• Include a link to the code in a comment at the top of a file and the dep's license

See https://github.com/NiceNode/nice-node/blob/main/src/main/util/escapePath.js as an example of this

Some example deps to do this for:

• await-sleep
• i18next-cli-language-detector
• gha apple codesign certs
