Silence one of the duplicated "Loading" messages from run_dev()

[howardbaik]

In pkgload_load_all(), I set the default value of quiet to TRUE to suppress the output from pkgload::load_all().

This change addresses #1191.

Thanks a lot @howardbaik 🙏

I wasn't aware of this param for pkgload::load_all()

I've cherry-picked your commit in a new branch that is here (you'll still see the commit) : #1201)

I've moved things around a bit — I prefer that the pkgload_load_all function stays with the default param (if ever we need to call it again at some point), and change the param inside document_and_reload.

In case you were wondering, the function in bootsrap_* are a copycat of the default functions, with just a check that the package is installed.

I've also bump the version number and added an entry in the NEWS.

Thanks again.

I’m really glad I could contribute—thanks so much for all your work on golem. It’s been an absolute lifesaver.
