[py]: 🚀 Improve performance

[fenilgmehta]

Description

For each call to text_to_be_present_in_element_attribute(...) we are calling driver.find_element and get_attribute(...) twice. This PR reduced both of them to one.

Motivation and Context

Possible performance optimization and remove redundant calls to driver.find_element and get_attribute(...)
