Typo fix

"Secret" should be plural "Secrets" in this context.

This title exists in Symfony 4.4 https://symfony.com/doc/4.4/best_practices.html#use-secret-for-sensitive-information I think the PR should target 4.4.

What's the best way of updating the PR to target 4.4? I tried to change the base via github but it brought across hundreds of other commits.

@andyexeter

• easiest method: close this PR, edit the file from the 4.4 branch and open a PR targeting 4.4
• more complicated method: rebasing may be too much work, but you can checkout the 4.4 branch locally, cherry-pick your commit, then push force on the branch of this PR, and finally change the targeted branch in this PR

We can merge it against 4.4 no problem 😃
