Bump xregexp from 4.2.4 to 5.0.1

[dependabot]

Bumps xregexp from 4.2.4 to 5.0.1.

Release notes

Sourced from xregexp's releases.

v5.0.1

• Hotfix for broken npm package.
• Adds docs folder with extensive documentation.

v5.0.0

Breaking Changes

• Enable the namespacing feature by default for alignment with ES2018 (moves named capture properties to the groups object of matches and to the last argument of replacement callbacks): slevithan/xregexp#316
• Handle ES2018 capture names (mostly this adds support for an extended set of Unicode characters, but it also prevents using a number as the first character in a capture name): slevithan/xregexp#247
• Remove support for Unicode blocks, for alignment with ES2018 (use Unicode scripts instead): slevithan/xregexp#225

Improvements

• Support optional 'Script=' prefix (from ES2018 syntax) for Unicode script tokens: slevithan/xregexp#225
• XRegExp.matchRecursive: Add delimiter and position info to error when unbalanced delimiters are found: slevithan/xregexp#293
• Avoid inserting unneeded (?:) into native regex source in more cases: slevithan/xregexp@076f950 and slevithan/xregexp@d78a262
• Defer to native flag s in ES2018 environments: slevithan/xregexp@98abea8

Bug Fixes

• XRegExp.exec: Preserve the groups object that comes from native ES2018 named capture: slevithan/xregexp@c4a83e7
• XRegExp.exec: Set the groups property to undefined if there are no named captures: slevithan/xregexp#320
• XRegExp.escape: Escape whitespace in a way that works with ES6 flag u: slevithan/xregexp#197
• XRegExp.replace: Throw when using native named capture and a numbered backreference one higher than the number of captures in the same regex: slevithan/xregexp#317
• XRegExp.replace: Fix edge case issues with replacement text syntax: slevithan/xregexp#318

v4.4.1

• Add browser field to package.json to fix webpack: slevithan/xregexp#308

v4.4.0

• Upgrade to Unicode 13.0.0
• Add TypeScript definitions and tests #285 #286 #288
