RC1 is out, `5-1-stable` has been created, figured it was time to start
updating this stuff :)

Rename local variable name `current_user` to `verified_user` [ci skip]

Related #28570

Rename local variable name `current_user` to `verified_user` [ci skip]

Assigning local variable named `current_user` in the condition is
confusing.

This reverts commit 296d024b, reversing
changes made to e341d835.

We aren't trying to compare to current_user, we're assigning that variable.

Remove `CollectionProxy#uniq`

Since #28473 `uniq` is delegated to `records`, so `CollectionProxy#uniq`
is unnecessary.

Document AC::Connection::Authorization#reject_unauthorized_connection

List options for `rails new --webpack=WEBPACK`

This method is repeatedly used throughout the docs (in the [AC::Connection docs](https://github.com/rails/rails/blob/12b684985837bc8ee9ad15c174cf4e07ca82d7c4/actioncable/lib/action_cable/connection/base.rb#L28), the [AC README](https://github.com/rails/rails/blob/12b684985837bc8ee9ad15c174cf4e07ca82d7c4/actioncable/README.md#a-full-stack-example), the [AC Guides](https://github.com/rails/rails/blob/12b684985837bc8ee9ad15c174cf4e07ca82d7c4/guides/source/action_cable_overview.md#connection-setup)), but not actually documented itself and seemingly not supported for public use based on its current `private` status.

This actually makes the method public and documents it.  The actual behavior that’s documented here is implemented [here](https://github.com/rails/rails/blob/12b684985837bc8ee9ad15c174cf4e07ca82d7c4/actioncable/lib/action_cable/connection/base.rb#L213-L219), via [this rescuing of the UnauthorizedError](https://github.com/rails/rails/blob/3dd1de8ba4d5862b01e7f5dd3878b21fd98b443b/actioncable/lib/action_cable/connection/base.rb#L172).

The method is [already tested here](https://github.com/rails/rails/blob/25473baf409185638073fe2f016f4b9dda284e50/actioncable/test/connection/authorization_test.rb#L17-L29).

Fix `LogSubscriber` to allow legacy `binds`

Don't add a dummy API key to every new Rails app

When you type `rails new -h`, the `--database=DATABASE` options display
this useful message:

> Preconfigure for selected database (options: mysql/postgresql/sqlite3/oracle/frontbase/ibm_db/sqlserver/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc)

However, the `--webpack=WEBPACK` option only displays this:

> Preconfigure for app-like JavaScript with Webpack

so it's hard to know *which* values are valid for `WEBPACK`.

This commit improves the help message to display:

> Preconfigure for app-like JavaScript with Webpack (options: react/vue/angular)

The implication of this commit is that the list needs to be manually updated
whenever rails/webpacker adds support for a new framework.

However, I don't imagine this list to change very frequently, and I think that
the benefit of display the list to the users is greater than the hustle of
updating the list when needed.
