Instead of an output/ folder, output the tests directly into the folder where they live.
Add some minimal instructions for regenerating the tests.
This code hasn't been touched in a while, so it's probably good to bring in the newest versions of the dependencies. We can easily tell if there was any incompatible effect on the output. The latest version of filenamify requires using ES modules. We also have to adapt to a breaking change in regexpu-core (see mathiasbynens/regexpu-core#49). Also convert the dependencies to devDependencies, since this tool is not necessary for executing test262.

The optimizations from commit e558b29 were never incorporated into the upstream test generator. This does so now. As far as I can tell, the changes to the Unicode ranges are purely cosmetic. Some are formatted as 6-digit hex numbers instead of 4-digit. Others move the low-surrogates range 0xDC00-0xDCFF to the beginning of the array, but the union of the ranges is still the same.
These are unused parameters and variables, and all have no effect on the output.
Add the `generated` flag, and update the link to the generator script.
This is necessary so that updates to the tests without corresponding updates to the generator script will be flagged in CI runs.
As per the package.json docs, these are optional if the package is not being published.

While we're touching this we may as well update the quote from ECMA-262 to match what it currently says.

Our config files specify two-space indents for JS files. These scripts were probably written before that was a thing. Update the indentation of the script and the generated tests all in one go.
Applying only to .travis.yml seems to be a relic from when that was the only YAML file in the repo. Extend it to all YAML files. Likewise, we have .mjs files now in the regexp-generator tool. Extend the same indentation from .js files to cover them as well.

Rather than mess with the Circle-CI images to get one that has both Python and Node installed, I'll migrate the linter and test generation jobs to GitHub Actions where they can run on the (Context: the |

https://github.com/bocoup/test262-regexp-generator was used to generate the tests in
test/built-ins/RegExp/CharacterClassEscapes/. It makes sense for this script to live in the same repo as the tests it generates. Especially since in the meantime, the tests themselves have gotten out of sync with the upstream.This imports the script, modernizes and cleans up the code, implements the changes necessary to match the changes made in the meantime to the tests, and integrates the script into the build process.
