If `tinytex` is installed through CRAN, render to PDF won't work due to `scrreprt.cls` not being found.

Error:
```
updating tlmgr

compilation failed- no matching packages
LaTeX Error: File `scrreprt.cls' not found.

                {amsmath,amssymb}^^M 

see Report.log for more information.
```

To resolve, uninstall `tinytex` and remove it. If you try to remove tinytex through the quarto CLI, it will refuse because tinytex was not installed by quarto.
```
tinytex::uninstall_tinytex()
remove.packages("tinytex")
```

Then install using quarto's recommended method.
```
quarto tools install tinytex
```

Systems tested:
- M1 Max MacOS 12.4 Beta (21F5048e)
- Intel MacOS Hackintosh 12.3

I'm not sure what the best solution for this would be. Either quarto could suggest overwriting other installs or warn that `tinytex` should be installed through the quarto CLI so that all components are available.
