Create Security Policy

[diogoteles08]

Closes #3691

I've created the SECURITY.md file following a GitHub's template and considering that you'd request that users report vulnerabilities through the security advisory, which is a handy new GitHub feature, but it's still in beta and has to be manually enabled by a maintainer.

If you're interested in this feature, you can activate it following this steps:

1. Click on this link to go to Code security & analysis section on your repo's settings
2. Click "Enable" for "Private vulnerability reporting (Beta)"

However, if you'd rather not use this feature, you can also request users to report vulnerabilities to an email. If that's the case, let me know which email you would like to receive the reports and I can submit the change.

Additionally, feel free to edit or suggest any changes to this document, it is supposed to reflect the amount of effort the team can offer to handle vulnerabilities.

Hey! This issue/PR has been idle for quite some time. Do you plan on considering these changes? If not, I'll probably wait up to 2 more months and close the issue.

Thanks!

Hey! I realized it actually doesn't make much sense to close without any position from the maintainers, as it can become of your interest on the future =)

I just updated the branch with latest main changes, let me know if there is anything else I can do to help.
