Bug in calculation of "_raw.flattenedPath"

[Oleksandr-Kei]

There is a problem with _raw.flattenedPath in generated JSON schemas for content files.
If there is a file with "index" in the end of filename then this part will be erased in resulted value of _raw.flattenedPath
For example:

• “search-by-index.mdx” will be resulted into “search-by-” in generated JSON schema;
• “find-element-by-index.md” will be resulted into “find-element-by-“
• “solution-documents/search-by-index.mdx” will be resulted into “solution-documents/search-by-“
• “solution-documents/find-element-by-index.md” will be resulted into “solution-documents/find-element-by-”

Here is a repo to reproduce the issue: https://github.com/Oleksandr-Kei/contentlayer-project

Actual problem could be in this line
Because /\/?index$/ covers not only cases of "something/index" and "index". But also cases like "something-index", "somethingindex", etc.

This should be addressed with the 0.3.4 release. 🎉
