[direnv] update envrcs in projects (#915)

## Summary

Ran `devbox generate direnv --force` in these directories.

Note, now that we ensure packages are installed during this step for one
or two of these it took a short while, but better than
a long pause when `cd`-ing into the directory.

## How was it tested?

didn't test
