Merge different languages for language stats (#24900)

Fix #24896

If users set different languages by `linguist-language`, the `stats` map
could be: `java: 100, Java: 200`.

Language stats are stored as case-insensitive in database and there is a
unique key.

So, the different language names should be merged to one unique name:
`Java: 300`
