Remove echo code action

[giacomocavalieri]

This PR implements a code action to remove echo debug printing from the hovered expression

[inoas]

could there be a way to remove it from an entire module or whole src code? gleam fix?

Could be a nice addition, I haven't thought of it that much, for now it just deletes the one under the cursor

This needs to remove all of them to be useful I think. It's more key presses to run the code action than to delete the echo yourself if it only works for a single one.

[giacomocavalieri]

All echos under the selection or in the entire module?

[lpil]

The entire module please. Maybe the entire package?

[giacomocavalieri]

Ok! When should the action trigger? Anywhere in the file? Sounds a bit annoying having that pop up every time if you have an echo in a module

[lpil]

Agreed. When on an echo sounds good?

[giacomocavalieri]

Yeah sounds good to me, just to make sure we're on the same page: once on an echo we should offer an action "remove all echos from module" which will remove all echos, not just the hovered one?

[lpil]

Yes please

[giacomocavalieri]

This should be ready now!

[inoas]

This is great <3

gleam fix echo could remove remove all echos from the project?

[lpil]

Something like that would be useful. We'll need to think about what would be the right API, as it'll influence future changes too.

[lpil]

Super nice! Couple tiny notes inline

[lpil]

Thank you!!
