Issue Description

I added a step definition with a param (regular expression that should accept 2 different strings (collapse or expand) then in the C# method I know how to behave depending on the param value.

But the step definition that is not reconized in feature files...

Steps to Reproduce

[When(@"I click on summary card ""(expand|collapse)"" button")]
public void WhenIClickOnSummaryCardCollapseExpandButton(string cardAction)
{
   throw new PendingStepExpception();
}

But I've observed that if there is other params it works :

[When(@"I click on summary card ""(expand|collapse)"" button with label ""([^""]*)""")]
public void WhenIClickOnSummaryCardCollapseExpandButton(string cardAction, string label)
{
   throw new PendingStepExpception();
}

This is likely because specflow since 4.0 allows both cucumber and regular expressions. This is automatically determined, but for this this step it makes an incorrect conclusion. To work around this you can write down the step as follow: @"^I click on summary card ""(expand|collapse)"" button$" to ensure it is always detected as a regular expression.
