Replace IDE 2.x configuration file content with link to source

Arduino IDE 2.x allows the user to customize the output of the "Auto Format" feature via a configuration file.

This system is documented in the "Customizing the Auto Formatter Feature" tutorial.

When the user customizes the formatter, their configuration file is used exclusively by the formatter tool rather than
being merged into the standard configuration. Since the user is likely only interested in modifying a small number of
specific aspect of the standard configuration (e.g., wishing to use "broken" rather than "attached" braces), they will
find it convenient to use Arduino's standard configuration as a base for their custom configuration. For this reason,
the standard configuration is offered in the tutorial.

Previously, the full YAML code of the standard configuration was included in the tutorial page itself. This was the best
approach at the time the tutorial was created because what was the canonical source in the Arduino IDE code base is in a
format not usable in this application.

Since that time, the ClangFormat native YAML file has been published in a dedicated permanent location where it is
hosted as the canonical source for all projects that use the configuration. This enabled the removal of the
configuration code from the tutorial, replaced by a link to the source file.

This change provides the following benefits:

### Reduce maintenance burden

The configuration code must be updated periodically in parallel to bumps of the version of ClangFormat used by Arduino
IDE 2.x and other Arduino development tools.

This is handled as a matter of course in the canonical source file, but the copy hosted in the tutorial content would
have needed updates as well (or else become outdated).

Pointing the reader to the source ensures they will always have the current configuration without any need to maintain
the documentation content.

### Improves approachability of tutorial

The configuration code added a large block of complex YAML to the tutorial. Although it will be necessary for the reader
to eventually work with this code, they don't have any need to browse through it while reading the tutorial. So having
the code as part of the tutorial content didn't add anything of value and also harmed the readability.
