ml_word_prob_dict.json in en2indic v1.0 is malformed, causing JSONDecodeError

[vvtrip]

Hi AI4Bharat team,

While using XlitEngine with lang2use=["ml"] and rescore=True, I ran into a JSONDecodeError when loading the Malayalam word probability dictionary.

Error-
JSONDecodeError: Expecting ',' delimiter: line 9782443 column 109 (char 1172307968)

This gets resolved by adding the missing curly brace at the end

.

Please review and add upstream if valid.

Thanks!
