Enable pnpm mode to catch issues earlier

[tido64]

Despite our best efforts, we cannot catch all pnpm related issues before they hit users. We need to be more proactive and catch them earlier. This means that we need to enable pnpm mode.

To enable pnpm mode:

diff --git a/.yarnrc.yml b/.yarnrc.yml
index f59a253e..b2cfdf1f 100644
--- a/.yarnrc.yml
+++ b/.yarnrc.yml
