Add label glob pattern support for removal

[ncalteen]

This pull request introduces a major update to the label management action, adding support for glob pattern-based label removal and refining input validation. The changes enhance functionality, improve error handling, and update the version to 3.0.0. Below are the most important changes grouped by theme.

Label Management Enhancements:

• Added support for label_patterns input to allow removal of labels matching specified glob patterns.
• Updated the labels and label_patterns inputs to be optional, with validation ensuring at least one is provided for removal operations.

Input Validation Improvements:

• Enhanced input handling by trimming whitespace and ensuring empty inputs are ignored. Added warnings for unsupported combinations, such as label_patterns with the add action.
• Added error handling for scenarios where no labels or patterns are provided for removal, or no labels are provided for addition.

Test Coverage Expansion:

• Added new test cases to validate the behavior of label_patterns, including matching patterns, empty inputs, and unsupported combinations.
• Mocked the get method in octokit to simulate fetching existing labels for pattern matching.

Documentation Updates:

• Updated README.md to reflect the new functionality, including examples of how label_patterns can be used alongside traditional label inputs.

Versioning:

• Bumped the package version to 3.0.0 to indicate breaking changes and new features.
