Allow string in 'root_sass' configuration

[smnandre]

Allow both string and array to configure root_sass. (follows discussion here

symfony_cast:
    root_sass: '%kernel.project_dir%/assets/scss/app.scss'

symfony_cast:
    root_sass: 
        - '%kernel.project_dir%/assets/scss/app.scss'

Magic done in the dependency extension, so it does not impact any domain code

Update: still think the documentation / recipes should contains the array version, as it's easier to understand that multiple values are allowed, and how to add them :)

Easy win, thanks!

Why not use both? :) I think we can show "string" example first (as it will fit most users), but below mention you can specify more values with an array. Wdyt?

[smnandre]

Of course, even better :)

Just anticipated issues/requests "how can i use multiple pathes" elsewhen :)

@bocharsky-bw, @smnandre, I update my PR #52 to update the docs with the array version :)

Thank you!

I just discover this could be written in a cleaner / shorter way:

->beforeNormalization()->castToArray()->end()

CF: https://symfony.com/doc/current/components/config/definition.html#array-nodes

Should i update the code ?
