[DOC]: use pnpm add <pkg> instead of pnpm install <pkg>

[jferrettiboke]

It should be pnpm add <pkg> instead of pnpm install <pkg>.

pnpm install is used to install all dependencies for a project while pnpm add <pkg> is used to install a package and any packages that it depends on.

More info (official source):

• https://pnpm.io/cli/add
• https://pnpm.io/cli/install

---

pnpm install <pkg> does the same as pnpm add <pkg> today, but it might stop functioning that way in future versions since the official docs clarify the difference between the two. It might be that pnpm install <pkg> was used in past versions, and the PNPM team didn't want to remove support for it right away after introducing pnpm add <pkg>.

@jferrettiboke weird github issue where the test suite didnt run (cant merge without it...). - can you bump a commit to this to retrigger them? (add whitespace to a README or something) id be happy to do it but im on an airplane and the wifi is terrible :)

@jeffchuber I think you have to click on "Approve and run".

@jferrettiboke, the PR title check fails. Can you do me a favor and update the title to start with [DOC]: then make a tiny change in a new commit so that the PR check runs again.

@tazarov Done. ✅
