GEODE-10465: Fix RAT failures by adding missing **/bin/** exclusion

[sboorlagadda]

This commit addresses RAT (Release Audit Tool) failures that occur when IDE-generated bin/ directories are present in the workspace. The issue was caused by a missing exclusion pattern that should have been included during the build system refactoring in May 2022.

Root Cause Analysis:

• In April 2017, /bin/ exclusion was added to RAT configuration (commit 4a09e88)
• Later removed due to legitimate bin/ folders in source tree (commit 39c72b2)
• During May 2022 build system refactoring (commit 509c0c6), the RAT configuration was moved from gradle/rat.gradle to build-tools/scripts/src/main/groovy/geode-rat.gradle
• The /bin/ exclusion pattern was inadvertently omitted from the new configuration

Problem:

• IDEs (Eclipse, IntelliJ) generate bin/ directories containing compiled classes, test resources, and other build artifacts
• These files lack Apache license headers and cause RAT failures
• The .gitignore already excludes bin/ folders, indicating they are build artifacts

Solution:

• Add '/bin/' exclusion pattern to RAT configuration
• This prevents RAT from scanning IDE-generated build artifacts
• Consistent with existing exclusions for other build directories (/build/)
• Aligns with .gitignore patterns that already exclude bin/ folders

Testing:

• Verified RAT passes with and without bin/ directories present
• Confirmed exclusion works for files without license headers in bin/ folders
• No impact on legitimate source files that require license headers

This fix prevents future RAT failures for developers using IDEs that generate bin/ directories during normal development workflow.

For all changes, please confirm:

• Is there a JIRA ticket associated with this PR? Is it referenced in the commit message?
• Has your PR been rebased against the latest commit within the target branch (typically develop)?
• Is your initial contribution a single, squashed commit?
• Does gradlew build run cleanly?
• Have you written or updated unit tests to verify your changes?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?

Thanks for taking care of this issue, @sboorlagadda . LGTM.

Hmm, ideally RAT should already ignore all files that are in .gitignore , I wonder why that doesn't seem to be working for Geode. I suppose it may be because the gradle-rat plugin is still at an earlier rat version (eskatos/creadur-rat-gradle#28)

Awesome! Thanks for the heads up. I will wait for 0.17 release and upgrade it. But for now we can go ahead and include this exclusion as it is annoying to deal with in local development
