Change Coolered DAI description

[zthreethree]

In protocol metrics on the dashboard (https://app.olympusdao.finance/#/dashboard) in the table for Holdings, the entry "DAI - Borrowed Through Cooler Loans" should be renamed to "DAI - Loaned out Through Cooler Loans" or "DAI - Lent Through Cooler Loans" as the dashboard is showing the balance sheet from treasury's perspective. Current description can lead new readers to think that DAI is borrowed by the treasury. (example: https://discord.com/channels/798328113087119371/1083661539648745483/1181355122169757788)
