Cucumber language server crashes when test definition in the C# have inline regex case insensitive settings

[EnisBiberovic]

👓 What did you see?

Suppose the following in the feature file:

When I start my Program

and in the step cs file

[When(@"(?i) I start my program")
public void WhenIStartMyProgram() {
...
}

The language server fails with
Invalid regular expression: /(?i) I start my program/: Invalid group

✅ What did you expect to see?

The language server is working and finding step definitions.

📦 Which tool/library version are you using?

VS Code extension version 1.10.0

🔬 How could we reproduce it?

Create an inline case-insensitive pattern matching, for example:
In the feature file:
When I start my Program

In the step definition file
[When(@"(?i) I start my program")
public void WhenIStartMyProgram() {

📚 Any additional context?

No response
