Typo in Contributing.md documentation

Just fixed a small typo in the documentation.

Remove `delete_sql` in sqlite3 adapter

`sql += " WHERE 1=1"` was introduced in 69cb942d.
But it is not needed. ref https://www.sqlite.org/lang_delete.html

Refactor `connection.insert_sql`

`connection.insert_sql` is almost the same as `connection.insert`.

[close #22917] Don't output to `STDOUT` twice

When `rails console` or `rails server` are used along with a logger set to output to `STDOUT` then the contents will show up twice. This happens because the logger is extended with `ActiveSupportLogger.broadcast` with a destination of STDOUT even if it is already outputting to `STDOUT`.

Previously PR #22592 attempted to fix this issue, but it ended up causing NoMethodErrors. A better approach than relying on adding a method and flow control is to inspect the log destination directly. For this `ActiveSupport::Logger.logger_outputs_to?` was introduced

```ruby
logger = Logger.new(STDOUT)
ActiveSupport::Logger.logger_outputs_to?(logger, STDOUT)
# => true
```

To accomplish this we must look inside of an instance variable of standard lib's Logger `@logdev`. There is a related Ruby proposal to expose this method in a standard way: https://bugs.ruby-lang.org/issues/11955

make generated controller test work correctly

Since the `#file_name` that not consideration for the namespace, if generate a controller with a namespace,
not the correct url helper generation, it had become an error to run the test.

Modified to generate the correct url helper, even if it is produced a namespace with controller.

Fix `connection#create` in PG adapter

This reverts related commits due to #22917.

This fixes the case when you try to render an html you know safe and the
file is named something.html. With this commit the content of the html
won't be escaped anymore because AV won't use Raw handler and choose
Html handler instead.

Autoload ReferenceDefinition class in abstract adapter so that it can be used by #add_reference in schema_statements

- Fixes #22916.

In Pg and Sqlite3, `:text` and `:binary` have variable unlimited length.
But in MySQL, these have limited length for each types (ref #21591, #21619).
This change adds short-hand methods for each text and blob types.

Example:

    create_table :foos do |t|
      t.tinyblob   :tiny_blob
      t.mediumblob :medium_blob
      t.longblob   :long_blob
      t.tinytext   :tiny_text
      t.mediumtext :medium_text
      t.longtext   :long_text
    end

Originally `connection#create` had aliased to `connection#insert` in PG
adapter. But it was broken by #7447. Re-alias `create` to `insert` for
fixing it.
