CodeSnippets can't display if languageTabs isn't present in docusaurus theme config

[ElliotFriend]

Hi, @sserrata!! 👋🏻

Super excited for the v3.0.0 release! I know it's been a lot of work, and I'm so thankful for everything you've done!!

Working on getting my project updated, and I hit a snag with the recent code snippets ordering feature. Looks like if siteConfig.themeConfig.languageTabs is either a) absent from the config, or b) an empty array, docusaurus will hit a runtime error complaining: TypeError: Cannot read properties of undefined (reading 'samples')

I think it might be crashing because if userDefinedLanguageSet is nullish, the filtered and then merged language set ends up being empty.

I was able to use patch-package to patch the built plugin. Here is the diff that solved my problem:
