none of the 3 following methods works anymore. Using version '0.2.37' get_insider_purchases() get_major_holders() get_mutualfund_holders()

~~Has Yahoo changed the API? Firefox -> Yahoo webpage -> F12 -> Network tab -> F5 -> inspect~~

Holders webpage doesn't appear to use API directly.

Hey just adding to this thread. The following are broken:

• insider_purchases
• insider_roster_holders
• insider_transactions
• institutional_holders
• major_holders
• mutualfund_holders

~~@bot-unit @JuliaLWang8 Can you advise on what the new API/fields might be, how to figure it out? (tagging because of https://github.com/ranaroussi/yfinance/pull/1728#issuecomment-1837160577)~~

I figured out a fix - ticker symbol needs to be appended to base URL, not added as a parameter:

https://query2.finance.yahoo.com/v10/finance/quoteSummary/AAPL

I'll leave as a nice task for #1084

Is it possible to use this method ".institutional_holders" in any version?

It would be essential for what I am working on currently.
