Subject: [PATCH 1/3] Remove `.idea/go-mail.iml`, update `.gitignore`

Deleted the `.idea/go-mail.iml` file which was committed in error and should not be part of the source code repository. Updated the `.gitignore` file to ignore the whole `.idea` directory, since it contains configuration files that are specific to each developers environment and not required for the project build. The changes in the repository will now make it more clutter-free and prevent unintentional commits of unnecessary files in the future.

Subject: [PATCH 2/3] Remove redundant vcs.xml file

The .idea/vcs.xml file was deleted because it is not needed for the project. It was initially created by the IntelliJ IDEA but we're managing version control configurations through another way, making this file redundant.

Subject: [PATCH 3/3] Update Go version to 1.21 in GitHub workflows

This commit updates the Go version from 1.20 to 1.21 on three GitHub workflow files: golangci-lint.yml, codecov.yml, and sonarqube.yml. The change ensures we use the latest Go version which is more efficient and comes with additional features, leading to improved project performance.
