Sha256 files from Gradle Distributions website should be provided as text files

SHA256 checksum at are referenced by a server as:

Content-Type: application/octet-stream

In prevents browser from having it opened directly in the browser window as a text file and the file has to be downloaded to see its content. It in turn, makes it harder to just open the file to copy-paste the value calling Gradle wrapper task:

./gradlew wrapper --gradle-version xxx --gradle-distribution-sha256-sum yyy

Changing the header value (by marking .sha256 files as text files in your web server) should fix it.
