Create a common function to write resulting JSON files to the releases directory.
It makes this task simpler to read and maintain, while making it modifiable at a central point in the future.
One example of such modification could be the sorting of the versions in a uniform way for all the scripts.
Fetch Java versions with their dates from https://www.java.com/releases/.
This script is using a new dependency: requests-html (https://requests-html.kennethreitz.org/). This is because https://www.java.com/releases/ needs JavaScript to render correctly. And for this to work requests-html automatically downloads Chromium because of its dependency to pyppeteer.
Chromium is downloaded into PYPPETEER_HOME, so the workflow has been modified to set this directory as a subdirectory of ~/.cache. Note that declaring the same environment variable from the python script does not work.
