Support request timeout for Java HTTP Client

[kwin]

Affected version

2.0.11

Bug description

Although Java HTTP client currently lacks proper support for request timeouts (https://bugs.openjdk.org/browse/JDK-8208693), this is provided through https://mizosoft.github.io/methanol/api/latest/methanol/com/github/mizosoft/methanol/Methanol.BaseBuilder.html#requestTimeout(java.time.Duration). As Methanol is already used in the context of #1620 it is easy to also implement request timeout now.

There is currently some WIP PR which adds that feature to open JDK: openjdk/jdk#27469

Not sure yet, how Methanol really implements the request timeout, raised mizosoft/methanol#154 to get clarification.
