[Site Creation] Fix screen titles visibility on tablet for the new & updated screens

[ovitrif]

Fixes #16464

Screen titles of the new and updated screens in the site creation flow were hidden on tablet.
This pull request fixes the bug by removing a line of code which apparently didn't change anything except for introducing this bug on tablets.

Preview

To test:

On Tablet

1. Start the site creation flow
   • expect the screen title Site topic to be displayed.
2. Choose or enter a site topic

3. Optional

if SiteNameFeatureConfig is enabled via manually returning true here:

• expect the screen title Site name to be displayed.
• Enter a site name

4. expect to land on the Choose a theme with the screen title displayed.

Regression Notes

1. Potential unintended areas of impact
   All 3 affected screens (Site Topic, Site Name, Site Theme) on mobile (portrait or landscape).

2. What I did to test those areas of impact (or what existing automated tests I relied on)
   Manual testing.

3. What automated tests I added (or what prevented me from doing so)
   N/a - Only UI changes.

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
