quarto list extensions shows internal extensions by default now

[cderv]

Discovered in quarto-dev/quarto-r#301

In v1.8 it was showing like this when no extensions

❯ quarto list extensions
No extensions are installed in this directory.

in v1.9, we have added quarto engine extensions, and Typst book using extension mechanism, and now they shows always

❯ quarto list extensions
Id              Version    Contributes
julia-engine    0.1.0
orange-book     0.1.0      formats  

However, this is confusing because no information that they are internal to quarto. And before those, any internal one where not shown as extensions (hugo-md, confluence, video and other shortcode, ...).

So I would say either we need to hide them also or we could make that more clear.

One impact: In quarto R 📦 I initially use quarto list extensions to know if some extensions were installed or not... now I can't use that without encoding the default internal ones.

Ideas:

• we could mark extension 'provider' or 'origin'

❯ quarto list extensions
Id              		Version    Contributes  Origin
julia-engine    		0.1.0					internal (or quarto-cli ?)
orange-book     		0.1.0      formats      internal
quarto-ext/fontawesome  0.1.0	   filters      local (or _extensions/ ?)

• quarto list extensions shows user installed one by default, with previous table view and quarto list extensions --all shows also internal in the list

I think this is not just about showing info... this is the whole design for those internal extension that probably need to be adapted - internal extensions can't behave like user ones.

Otherwise, you can do this

❯ quarto list extensions
Id              Version    Contributes
julia-engine    0.1.0
orange-book     0.1.0      formats

❯ quarto remove orange-book

? Are you sure you'd like to remove Typst Orange Book Format? (Y/n) » Yes

Extension removed.

❯ quarto list extensions   
Id              Version    Contributes
julia-engine    0.1.0

And this remove file in the installation directory of quarto

❯ ls -a C:\Users\chris\scoop\apps\quarto-prerelease\current\share\extension-subtrees\orange-book\
.gitignore  LICENSE  README.md

Leading to broken state... 😞
