create a GitHub Action workflow to build and publish an EXE file

[LovingThresh]

What's Changed

Added a GitHub Actions workflow to automatically build and publish Windows executables:

• Runs daily at 00:00 UTC
• Creates date-based versioned releases (e.g., v2025.03.20)
• Works on Windows runners for the entire process
• Generates SHA256 checksums for verification

Why

• Provides ready-to-use executables for users without building from source
• Eliminates manual release process
• Ensures daily availability of latest builds

Implementation

• Single Windows workflow using PowerShell
• Properly handles file uploads and release management
• Automatically replaces previous day's release

这个GitHub action更适用于 nightly build。建议做2个工作流， 将 nightly build 放在单独的工作流文件中，与正式发布区分开。正式发布只在每次打tag时运行。对于nightly build 建议 用单一固定的 "nightly" 标签每次构建会替换之前的 nightly 版本，通过 --prerelease 标记，明确标识为非正式版本。另外建议将中文注释改为英文注释。

Improved GitHub Actions Workflow for Automated Builds

What's Changed

Split the build process into two separate workflows for better organization and clarity:

1. Nightly Build Workflow

Added a dedicated workflow for automatic nightly builds
Runs daily at 00:00 UTC and on pushes to main/master
Creates a permanent "nightly" release tag marked as pre-release
Updates the same nightly release with each new build
Includes date in filename (e.g., PPOCRLabel-nightly-20250320.exe)
Generates SHA256 checksums for verification

2. Release Build Workflow

Added a separate workflow for official releases
Triggered only when version tags are pushed (e.g., v1.0.0)
Creates permanent version-based releases
Names executable files according to the version tag
Generates SHA256 checksums for verification

你这是ai生成的吧，跑起来有问题。

[LovingThresh]

Sorry, let me deal with it. What is the specific question?

[GreatV]

I've fixed the issues.

[LovingThresh]

I sincerely apologize. When pushing the code today at the office, I relied on my memory and inadvertently missed the requirements.txt file. I also later realized that the generated package size is different from the version I successfully built at home. But, most of the code itself is fine. I am still very sorry for this oversight.

Thanks for your contributions and please feel free to continue your contributions to the PPOCRLabel and the PaddleOCR community.

Daily builds may be too frequent, we need to delete this action and only keep the builds during releases.

[GreatV]

Can you submit a PR to delete this?
