Update README.md

We present **Pralekha**, a document-level alignment benchmark designed to evaluate various long-context parallel data mining strategies, comprising over 2 million documents, with a 1:2 ratio of unaligned to aligned document pairs across 11 Indic languages and English.
Each instance in the dataset is represented as a tuple (*n_id*, *doc_id*, *lang*, *text*).

In this structure:
- *n_id* serves as a unique identifier for each parallel document pair,
- *doc_id* uniquely identifies individual documents,
- *lang* indicates the document’s language using its ISO-3 code, and
- *text* contains the corresponding textual content in that language.
