Builds HTTPS Everywhere ruleset files for Brave.

Update xpiVersion in scripts/preloadHTTPSE.js to the latest release number from https://www.eff.org/https-everywhere. If there are rulesets that are broken and need to be disabled, add them to the exclusions list.

If there is a breaking ruleset format change, bump the version number in package.json by one major point release. (Ex: 5.2.21 to 5.3.0. The minor point number is no longer used and can be set to anything.)

npm run build

npm run upload [-- --prod]

Without the prod option, this uploads to the test bucket.
