💪 Support regex for selection in steps

[jd-solanki]

Hi,

Regex patterns are useful code that changes in the future.

Thanks for the support of Regex based step using pattern property. However, for selection (property) feature, tour still relies on line numbers.

It will be great if tour can support regex for selection as well. ATM, using regex for tour doesn't add selection even if we have selected region. Manually writing selection property in tour file isn't valid as well because it will rely on line numbers instead of patterns.
