Clears the `javaExecutablePath` on the Protobuf extension. This prevents absolute Java installation paths from being tracked as task inputs, avoiding cross-machine build cache misses and ensuring the task is fully relocatable. This is safe because `protoc` and `grpc` are configured to use native binaries rather than executable JARs.

Thanks, @erichaagdev. The Detekt changes are applicable to 3.5.x and later so I'll apply those separately. |

Overview
This PR improves build cache relocatability by fixing cross-machine cache misses in the Detekt and Protobuf tasks. Previously, absolute paths were leaking into task inputs, causing unnecessary cache invalidation between different environments (e.g., CI servers vs. local developer machines).
Changes
basePathon Detekt tasks to use a relative path from the root project. This prevents absolute paths from being used during analysis.javaExecutablePathon the Protobuf extension. This prevents absolute Java installation paths from being tracked as task inputs. (Note: This is safe becauseprotocandgrpcare configured to use native binaries rather than executable JARs).Impact
Normalizing these inputs ensures both tasks are fully relocatable. This will maximize remote build cache hits and prevent duplicate work across environments.
