Bump xo from 0.21.1 to 0.23.0 and fix errors

[dependabot-preview]

Bumps xo from 0.21.1 to 0.23.0.

Release notes

Sourced from xo's releases.

v0.23.0

Highlights

• In v0.22.0, we added support for .ts and .tsx extensions by default. This caused a lot of problems for non-TS projects, so it has been reverted pending a better solution.
• The quotes rule is now set to disallow using template literals when you're not using any interpolation. xojs/eslint-config-xo@ea693f3
• Removed the no-use-before-define rule. It has too many false-positives. xojs/eslint-config-xo@1257597

New rules

• require-await
• unicorn/prefer-exponentiation-operator
• unicorn/catch-error-name (See this thread if you're wondering why error is preferred over err)

All changes

xojs/xo@v0.22.0...v0.23.0
