Add back isMethod check in jedis instrumentation

[laurit]

isMethod got removed by automated review agent. Here instrumenting of constructors is not desired and also fails with

Pull request overview

This PR restores Byte Buddy’s isMethod() matcher in Jedis instrumentations to ensure only actual methods (not constructors) are instrumented, preventing constructor-advice application that can trigger Byte Buddy instrumentation errors (as seen for BinaryJedis()).

Changes:

• Add isMethod() to the public, non-static matcher used for Jedis advice application.
• Add the corresponding ElementMatchers.isMethod static import across Jedis 1.4 / 3.0 / 4.0 instrumentations.

instrumentation/jedis/jedis-4.0/javaagent/src/main/java/io/opentelemetry/javaagent/instrumentation/jedis/v4_0/JedisInstrumentation.java	Restricts advice application to methods only (excludes constructors) for Jedis 4.x types.
instrumentation/jedis/jedis-3.0/javaagent/src/main/java/io/opentelemetry/javaagent/instrumentation/jedis/v3_0/JedisInstrumentation.java	Prevents constructor instrumentation for Jedis 3.x types (including BinaryJedis).
instrumentation/jedis/jedis-1.4/javaagent/src/main/java/io/opentelemetry/javaagent/instrumentation/jedis/v1_4/JedisInstrumentation.java	Aligns Jedis 1.4 instrumentation matching to methods-only to avoid constructor advice.
