Install fails for litsearchr

[andrea-foppiani]

Install fails with message:

> remotes::install_github("rmetaverse/metaverse", dependencies = TRUE)
Using github PAT from envvar GITHUB_PAT
Downloading GitHub repo rmetaverse/metaverse@master
Error: Failed to install 'metaverse' from GitHub:
  HTTP error 404.
  No commit found for the ref master

  Did you spell the repo owner (`elizagrames`) and repo name (`litsearchr`) correctly?
  - If spelling is correct, check that you have the required permissions to access the repo.

@andrea-foppiani I stumbled into the same error. After going through the install instructions for that particular package I found that the correct ref is "main", and no longer "master"

Here is the command to install litsearchr:
remotes::install_github("elizagrames/litsearchr", ref="main")
