Add release workflow and update AWS credentials provider chain (#1)

### TL;DR

Added GitHub release automation workflow and updated AWS credential provider chain.

### What changed?

- Added release automation with GitHub Actions:
  - Created `.github/release-drafter-config.yml` to define release notes format with Korean category labels
  - Added `.github/workflows/release.yml` to automate plugin publishing when release tags are pushed
- Updated AWS credential provider chain in `Credentials.kt` to include:
  - Added `WebIdentityTokenFileCredentialsProvider` as first priority
  - Added `EnvironmentVariableCredentialsProvider` as second priority
  - Reordered credential providers for better precedence
- Bumped version from 0.0.2 to 0.0.3 in `gradle.properties`

### How to test?

1. Push a tag with format `release/*` to trigger the release workflow
2. Verify the release draft is created with proper categorization
3. Test AWS credential resolution in different environments to ensure proper provider precedence

### Why make this change?

- Streamlines the release process with automated changelog generation and plugin publishing
- Improves AWS credential resolution by adding support for web identity tokens and environment variables
- Enhances security by prioritizing more secure credential providers in the chain
