Hello,

There is a typo at the time of building the text for a minutely rule where the frequency is 1.

Expected output: every minute for 3 times.
Actual output: every minutes for 3 times.
Version: 2.6.4

I had a look at the source code and I have identified where the issue is. I have tried to create a PR but it is not allowed.

As you can see in the picture, for hourly rules it is using a different string depending on whether the rule is singular/plural. However, for minutely rule it is always using plural string.
