Changes in Profile List View [A11y] [BLOCKED]

[Arjupta]

Describe the bug(Considering only admin profile)

The Profile List Fragment under Edit profiles option of Administrator Controls have certain views which are not fully compatible from the Accessibility point of view.

Issue 1 - The Contrast ratio (foreground to background) of text inside profile_list_profie_view is 2.68 but the suggested one is 4.50 (under profile_list_fragment)
Issue 2 - Multiple items have the same Description as that of textview inside the toolbar present in the profile_edit_activity

To Reproduce
Steps to reproduce the behaviour:

1. Start the Accessibility Scanner App on your device
2. Open the Oppia Android App and scan the screenshots with the Accessibility Scanner
3. You will see the tests that are not passed by that screen
4. Repeat this for other screens

Expected behaviour
All the tests must be passed by scanning the screenshots for both Tablet and Mobile Devices in every orientation.

Let's change the subtext to #555555. LMK what contrast ratio that would make it and if it is sufficient enough.
