Describe the bug
Read-only fields are harder to read in the high contrast theme
To Reproduce
Steps to reproduce the behavior:
Expected behavior
A user has asked if it is possible to lighten the read only fields.
Screenshots
Comment from a user regarding the read-only field. "The background colour in grids is really dark where the value is non-maintainable once saved. The colour is fine when it's just individual fields like the Application Number but really doesn't look good in a 'block' like the grid."

When the form is in the light theme the read-only datagrid field, is a lighter shade compared to the field that is also read-only.

@kayiuho Could you please take a look at this and comment with what you would suggest we do, so that the assigned dev can implement?
I noticed that there's a difference between the screenshot and the EP demo. In the screenshot, read-only state BG is implemented with #999999. In the EP demo, .datagrid td.is-readonly (in High Contrast) is #BDBDBD.

I can confirm that with the current version the BG color is #BDBDBD. No action required as it has been corrected.

This issue is now resolved.
