Besides the works of Dabholkar and Saraswati Gangadhar, what other Guru biographies are mentioned in the text?

The source material in Chapter 0 acknowledges other Guru biographies beyond the two most famous ones. It mentions a detailed and scholarly biography written by Shri Samarth Sadguru Tembhe Swami, also known as Vasudevanand Saraswati Maharaj. However, it is noted that this work had not become as famous as the one by Shri Saraswati Gangadhar. Additionally, there is a mention of a Guru biography written by Shri Samarth Sadguru Dattatreya Maharaj of Balekundri, but the text indicates that this particular work did not yet seem to have been printed or published.
