From previous discussion about removing lodash dependencies, it sounds like we can use the widely-used escape-string-regexp library to replace the functionality provided by lodash/escapeRegExp.

As noted in that discussion, this module requires Node 10 or greater, and that won't be guaranteed in babel until version 8, so this changeset is based against the next-8-dev branch.

@jayaddison Updating the yarn.lock should fix the e2e error.

Note that compared to _.escapeRegExp, escape-string-regexp also escapes - to \\x2d: https://github.com/sindresorhus/escape-string-regexp/blob/b3eb767656fe6dbb8c8dbf31746171cfb7b23b78/index.js#L12

Although unnecessary as this is for PCRE compatibility, I think it is acceptable to replace _.escapeRegExp, which also applies toString on the input -- but we never pass a non-string input to escapeRegExp.

Thanks!

Eh, sort of a nitpick of myself here, but I realized I should have said 'yes' to the 'dependency changes' question in the pull request description Q&A. I'll edit that in the description now (even though it's post-review and post-commit).

Oh thanks! That table is only used by us to add PR labels, which are used in the changelog and by reviewers!

Good to know, thanks @nicolo-ribaudo!
