fix(android): Remove toggle for "Always Show Banner"

[darcywong00]

Fixes #12376

The "Always show banner" toggle was originally reserved for future features. As of Keyman 17.0 though, there will always be a banner above the OSK (displaying either suggestions or an HTML bannner).

This removes the toggle from the Keyman settings screen. And also updates the in-app help.

User Testing

• Setup - Install the PR build of Keyman for Android on a modern device/emulator. (I noticed the emulator for Android 8.1 [API 27] has an old version of Chrome so the suggestion banner is broken)

TEST_BANNER TOGGLE_REMOVED - Verifies banner toggle is gone

1. Launch Keyman for Android and dismiss the "Get Started" menu
2. With the default sil_euro_latin keyboard start typing
3. Verify suggestion banner provides suggestions.
4. Open Keyman settings
5. Verify the toggle to always show banner is removed (it used to come after "Vibrate when typing")
6. Exit Keyman settings
7. From the Keyman menu, open the Info page (in-app help)
8. Scroll down to Using Keyman for Android heading and select Using the Settings Screen
9. Verify the screenshot for Step 2) does not include Always show banner
10. Scroll down to Vibrate When Typing section
11. Verify the next section is Show "Get Started" on startup

I tested this issue with the attached "Keyman 18.0.114-alpha-test-12430" build on the Android 14 mobile(physical device) and Android 12(emulator). Here is my observation.

• TEST_BANNER (Passed):

1. Installed the "Keyman-18.0.114.apk" file from the PR build.
2. Open the Keyman app.
3. Close the "Get Started" menu
4. Verified the suggestion banner provides suggestions while typing text in the keyman's note tab.
5. Open the settings menu by clicking the ellipsis button.
6. Verified the toggle to "always show banner" is removed.
7. Close the keyman's settings menu.
8. Open the "Info" page by clicking the ellipsis button.
9. Scroll down to the "Using Keyman for Android" heading and select "Using the Settings Screen"
10. Verified the step 2 screenshot did not have the "Always show banner"
11. Scroll down to the "Vibrate When Typing" section
12. Verified the next section is "Show 'Get Started' on startup"
    It works great for me. Thank you.
