Support for JSON5

[ikhoon]

Motivation:

This PR enables JSON5 features available in Jackson, preserves JSON5 content as-is, and still provide the same support such as JSON Path that was available for JSON.

Limitation:

Comments in JSON5 content will be lost when a JSON Patch operation is applied. If you want to preserve the original content, you must use UPSERT_JSON.

Related: #538

Modifications:

• Java implementations)
  • Json5 is introduced to deserialize JSON5 content.
    • Hexadecimal integers (0xdecaf) and trailing decimal points (8675309.) are unsupported due to the limitation of Jackson.
    • Thanks to @ks-yim, most of the code comes from #655
    • Json5 is used in Entry and JsonChange to convert JSON5 file into JsonNode.
  • Updated Util.JSON_FILE_PATH_PATTERN to allow the .json5 extension.
  • CentralDogmaRepository.importDir() now uploads raw JSON files without normalization.
  • Fixed AbstractGitMirror to mirror raw JSON content instead of the normalized one.
• Webapp implementations)
  • Implemented JSON5 tokenizer for Monaco editor to provide syntax highlighting.
    • It aligns Jackson's JSON5 features.
  • Add json5 dependency to validate JSON5 content.
  • Fix NewFile.tsx to extract a file extension and set it to language for Monaco editor.
    • Previously, it was hardcoded to json so other languages such as YAML were not supported.

Result:

• Central Dogma now provides first-class support for JSON5.
• Closes #538

It seems trivial to also add support for yaml as well.

I'm on the same page.
