Tesla Builder deprecation warning on compilation

[ddon]

Problem

When compiling a project that depends on oauth2, Tesla 1.15+ emits a deprecation warning:

warning: `use Tesla.Builder` and `use Tesla` are soft-deprecated. It will be removed in future major version in favor of
Runtime Configuration instead. Please share your feedback at https://github.com/elixir-tesla/tesla/discussions/732

If you can turn off this warning, add the following to your config.exs:

    config :tesla, disable_deprecated_builder_warning: true

  lib/tesla/builder.ex:9: Tesla.Builder."MACRO-__using__"/2

This warning originates from oauth2's internal use of use Tesla / use Tesla.Builder, and affects all downstream consumers (ueberauth strategies like ueberauth_google, ueberauth_apple, ueberauth_github, ueberauth_facebook, etc.).

Environment

• oauth2 v2.1.0
• tesla v1.15.3 (latest: v1.16.0, warning persists)
• Elixir 1.19.5

Workaround

Downstream apps can suppress the warning with:

config :tesla, disable_deprecated_builder_warning: true

But ideally oauth2 would migrate to Tesla's Runtime Configuration API as described in elixir-tesla/tesla#732.
