Provide more info "This command must be executed inside a Quasar project folder" failure state

[ajmas]

When Quasar can't find the quasar.config.* (.js, .ts, .mjs, .cjs) file, it declare the project is not a quasar project, with no more information in regular mode or debug mode. For this reason it would be useful to either have verify option or update the error state to provide an output such as follows, even it is limited to -d argument:

No `quasar.config.<ext>` (where `<ext>` is one of .js, .ts, .mjs, .cjs) found.
Note: if upgrading from a previous Quasar version you will need to rename and uydate your `quasar.conf.*` file

Details

I recently upgraded my project to use a more recent version of Quasar and it started failing with the following error:

This command must be executed inside a Quasar project folder
Investigating the Quasar command revealed that it was now looking for quasar.config.* instead of quasar.conf.*.

Until I looked at the source code, it wasn't clear what was causing this failure. I had tried the following, but none provided any more clarity:

quasar dev
quasar build
quasar build -d
quasar info

For this reason it would be good for the command to be updated to provide the extra info.
