[dependabot]

Bumps highlight.js from 9.18.1 to 9.18.5.

Changelog

Sourced from highlight.js's changelog.

Release v9.18.5

Version 9 has reached end-of-support and will not receive future updates or fixes.

Please see VERSION_10_UPGRADE.md and perhaps SECURITY.md.

• enh: Post-install script can be disabled with HLJS_HIDE_UPGRADE_WARNING=yes
• fix: Deprecation notice logged at library startup a console.log vs console.warn.
  • Notice only shown if actually highlighting code, not just requiring the library.
  • Node.js treats warn the same as error and that was problematic.
  • You (or perhaps your indirect dependency) may disable the notice with the hideUpgradeWarningAcceptNoSupportOrSecurityUpdates option
  • You can also set HLJS_HIDE_UPGRADE_WARNING=yes in your envionment to disable the warning

Example:

hljs.configure({
  hideUpgradeWarningAcceptNoSupportOrSecurityUpdates: true
})

Reference: highlightjs/highlight.js#2877
