REQ - How do I install the {gt} package?

[terrymclaughlin]

Is your feature request related to a problem? Please describe.
When trying to use gtsave() to save a table to cl-out I get the error:
"google-chrome and chromium-browser were not found. Try setting the CHROMOTE_CHROME environment variable or adding one of these executables to your PATH."

Describe what you'd like
I'd like instructions on how to install the {gt} package successfully in Posit Workbench.

Describe alternatives you've considered
This is required for pre-existing scripts that produce routine outputs.

Additional context
I'm using R version 3.6.1; {gt} version 0.8.0 and {webshot2} 0.1.0

I didn't have this problem when using RStudio.
