build(deps): Bump com.squareup.okhttp3:okhttp-bom from 5.3.2 to 5.4.0

[dependabot]

Bumps com.squareup.okhttp3:okhttp-bom from 5.3.2 to 5.4.0.

Changelog

Sourced from com.squareup.okhttp3:okhttp-bom's changelog.

Version 5.4.0

2026-06-08

• New: Add superpowers to interceptors. Interceptors can now override anything settable on OkHttpClient.Builder, such as the cache, connection pool, socket factory, and DNS. We expect this will allow most users to use interceptors everywhere, insted of mixing and matching interceptors with custom Call.Factory wrappers.
• Fix: Limit each HTTP/2 response to 256 KiB of total headers.
• Upgrade: [kotlinx.coroutines 1.11.0][coroutines_1_11_0]. This is used by the optional okhttp-coroutines artifact.
• Upgrade: [GraalVM 25.0.3][graalvm_25].
• Upgrade: [Okio 3.17.0][okio_3_17_0].

Required CircleCI remains failing after the allowed three concrete fix attempts, so this cannot be approved or merged. I fixed the outdated Request.create calls in JavaLoggerTest and LoggerRebufferTest, formatted those updates, then fixed Slf4jLoggerTest by adding the missing feign.Util import and updating its Request.create calls. The current failure is now validation/src/test/java/feign/validation/BeanValidationMethodInterceptorTest.java:79: String cannot be converted to Request.Body. Per maintainer policy, I am stopping after three attempts rather than pushing another change.
