Add Russian language
Could you sign the DCO commits via the instruction here - 
https://github.com/NVIDIA/NeMo/pull/2230/checks?check_run_id=2612023734 Also seems test failed due to style formatting. Could you run `python setup.py style --scope nemo --fix` Could you rebase with the main branch? Seems incorrect branch was selected? The asr parts was refactored in order to be modular, could you apply those changes in the conflicting files? Most of them just had path changes- but manifest and parsers now belong to nemo/collections/commons/parts instead of asr. Closed due to inactivity. Please reach out in order to resume work on it.
Add Russian yaml, class RUCharParser() and relative path support in __parse_item() 
Add "manifest_line_parser" argument and one more parser: __parse_open_stt()
