Remove AppBundle

[roukmoute]

The twig file is in app/Resources/views.
Fix error Unable to find template "AppBundle:Form:fields.html.twig"

[stof]

Using the Form/fields.html.twig notation would be better, as this is what we use almost everywhere in the doc now

[stof]

note that this notation can be used only for Twig, not for PHP templates

[wouterj]

Actually, it should be form/fields.html.twig.

[roukmoute]

@stof: I must keep this notation for code-block:: php or for the section For the PHP templating engine[...] ?

[stof]

the PHP example needs to keep using the :Form notation yeah

[wouterj]

@roukmoute can you please update the first 3 code blocks to use form/fields.html.twig and the other 3 to :form:fields.html.twig?

If you don't have time, feel free to say so and I'll finish this PR.

[roukmoute]

Is it OK ?

[wouterj]

Thank you for creating this PR & the patience with such a slow merge!

I've merged your PR into the 2.3 version of the docs (resulting in a closed status on GitHub) and will merge it into the newer versions from there. I've also changed the format a little bit (to not use the colon syntax for twig and reference PHP files in the second code example) in 4a41252.

Thanks again! 🎄
