GitHub Action fails when using development version of renv (1.0.5.9000)

To resolve #1869, I upgraded to the development version of renv (1.0.5.9000). Some GitHub Actions using renv are now failing with an error:

2024-04-08T16:38:43.0699010Z Error in heredoc("\n      renv %1$s was loaded from project library, but this project is configured to use renv %2$s.\n      - Use `renv::record(\"%3$s\")` to record renv %1$s in the lockfile.\n      - Use `renv::restore(packages = \"renv\")` to install renv %2$s into the project library.\n    ") :

(see jabenninghoff/rdev#197 for full details)

This appears to be occurring because renv is not loaded when renv_bootstrap_validate_version() is called from renv/activate.R. I was unable to reproduce the issue locally, but it is reliably failing for my missing-deps.yaml and lint.yaml actions.

Looking through the logs, it seems that calling renv::install() seems to trigger the issue. Running install() is unexpectedly installing renv (and knitr) even though both are already installed.

After additional research, it appears that upgrading packages is the intended behavior. Closing in favor of #1871.
