Remove deprecation warning: "Rendering actions with '.' in the name is deprecated:"

Problem

When running specs following deprecation warnings are emitted

Rendering actions with '.' in the name is deprecated:

Why?

Using . in template names has been deprecated in https://github.com/rails/rails/pull/39164.

Proposed solution

For example:

Bad

render 'shared/logo.svg'

Good

render partial: 'shared/logo', formats: :svg

OR if the used view is a template:

render template: 'errors/access_denied', formats: :svg

Note, the additional partial: (or template:) and formats: options.
