[commonForm.style.js] text color fix in dropdown

[prabhjeevnijjar]

Description

This PR fixes #5242 #5232

Notes for Reviewers
`The behaviour of styling tag is not linear across browsers in different OS. This is also mentioned in the MDN docs. Behaviour of

Mac OS

• Background color and text color is picked by default based on browser theme, This works perfectly

Windows

• Shows white background all the time independent of the browser theme
• But text color can be changed by CSS,
• We were using -> props.theme.primaryColor [It changes the text color to white in dark theme, Which was the exact issue]
• I changed it to -> props.theme.textColor [Now it stays in a shade of grey]`
