Action View Docs: field_id and field_name examples [ci skip]

Several code samples for `field_id` and `field_name` cite the use of
[text_field_tag][]-style helper. That usage is incorrect. The helper
interface that `field_id` and `field_name` mimic is the
[text_field][]-style helper, without the `_tag` suffix.

[text_field_tag]: https://edgeapi.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#method-i-text_field_tag
[text_field]: https://edgeapi.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-text_field
