Subject: [PATCH 1/2] fix: update browserslist on install rather than on serve

Having serve depend on update-browserslist can cause a race condition
when you're using npx nx run-many because one process (update-browserslist) is
changing packages while others (serve-es, serve-fr, serve web-component) are
compiling from them.

Also, having serve depend on update-browerslist makes serve much slower on my
Windows machine, because the latter can easily take a minute.

We want to automate it, yes, but Del and I agree that on install is a better
time and place to automate it than on serve, and it's plently often enough to
satisfy our requirements.
