updating OTF on sponsors page

Please update the sponsors page https://www.torproject.org/about/sponsors/ to have an updated description for Open Technology fund. I have made these changes and would like for someone to make the changes live.

Here's the link https://gitlab.torproject.org/bekeela/tpo/-/blob/master/content/about/sponsors/otf/contents.lr Commit 658cd9513a5ca04ebfaa0bf4e21d983386113643
