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`
