chore: update repository URL with correct case sensitivity

The repository URL in package.json was updated to use proper capitalization
for the GitHub organization name, changing from lowercase "serverless-devs"
to proper case "Serverless-Devs" to match the actual GitHub organization.

更新仓库 URL 以使用正确的大小写

package.json 中的仓库 URL 已更新以使用正确的 GitHub 组织名称大小写，
将小写的 "serverless-devs" 更改为正确的 "Serverless-Devs" 以匹配实际的 GitHub 组织。
