Allow authentication header to not have to specify 'token=' key.

Fixes: https://github.com/rails/rails/issues/17108.
Correct test description for large integer test
Explain that default_scope also influences update_all

This was not explicitly stated before and I needed to try it out to be
certain. A little explicit statement in the API docs might help here.
Fixing documentation in JSON#from_json

Commit d67b289 introduced a tiny regression in the docs for #from_json,
true needs to be included when the root node is present.
Remove is_a? check when ignoring tables

Technically changes the API, as it will allow any object which responds
to `===`. Personally, I think this is more flexible.
Creates an ApplicationMailer and layout by default, including html and body tags to reduce spam score
Adding simple docs for ActionDispatch::Flash::FlashHash#to_session_value
adding nodoc to private methods
Do not rescue Exception in ParamsParser

Unlike ShowExceptions or PublicExceptions, ParamsParser shouldn't
transform exceptions like Interrupt and NoMemoryError into ParserError.
Removing unnecessary File.join calls
Reword documentation for update_all

It now contains a carefully formulated reference to the "current relation" which might help clarify that the receiving will generate its own scope, escaping the need for explicitly referencing `default_scope` which is, after all, just another way of specifying a scope and nothing special.
Don't center the routes table on routing errors
Document `String#html_safe` [ci skip]

It should be part of the documented public API, since we have an entire
section of the guides dedicated to it. Documented in a way that
addresses the concerns which kept it undocumented in the past.
Fix sprockets-rails dependency dance

Use sprockets-rails 2.2.x on base app and allow greater version
Merge pull request #17682 from ReneB/docs/update_all

Explain that default_scope also influences update_all
allow the "USING" statement to be specified on change column calls
oops, forgot to add the real assertion!
allow types to be passed in for USING casts

This allows us so abstract the migration from the type that is actually
used by Rails.  For example, ":string" may be a varchar or something,
but the framework does that translation, and the app shouldn't need to
know.
