Add a setting form where Tagify widget can be set as default when a supported field is created

A new settings form has been added, allowing users to suggest the Tagify widget as the default for supported entity reference types.

By default, the Reference section is hidden. It becomes visible when the user selects Suggest Tagify widget as default. In this section, users can modify which widget will be the default for each supported entity reference type. This feature enables users to even set Tagify User List as the default widget for the User entity reference type and Tagify for Taxonomy terms.

Once configured, any newly created entity reference field will automatically use the selected widget as the default.

Code looks good in general. Default config definition would be needed, though.

Also added a minor suggestion that might be out of scope.

Are tests also considered for this new feature?

#6 ✨ Add a setting form where Tagify widget can be set as default when a supported field is created Active I did not consider the test coverage at the begining of this implementation, but it makes a tons of sense.

Everything looks good to me!

Marking as RTBC.

It will be part of release 1.2.36
