Avoid truncation of 'Try Jetpack" button with big fonts

[ovitrif]

Fixes #17428

This PR ensures the Try the new Jetpack app button is not truncated with big fonts.
The issue was not reproducing for all languages, one of the languages it reproduced with is French.

I replaced the MaterialButton with a Button because I couldn't find any way to make the MaterialButton avoid truncation on the bottom sheet.

To test:

Test Case 1 - Big Fonts

0. Prerequisite: Enable the jetpack_powered_bottom_sheet_remote_field feature flag.
1. Set app language to French (Me → App Settings → Interface Language)
2. Set max font size via Accessibility settings on device.
3. Tap the "Jetpack Powered" badge on Me, or My Site → Home
4. Expect the primary button to show text on 2 lines (not truncated — see screenshots)
5. Rotate the device to landscape
6. Expect the primary button to show normally, with no issues

Test Case 2 - Regression

1. Restore default font size via Accessibility settings on device
2. Tap the "Jetpack Powered" badge on Me, or My Site → Home
3. Expect to see the Try the new Jetpack app styled as before, with no visual regression
4. Rotate the device to landscape
5. Expect to see the Try the new Jetpack app styled as before, with no visual regression
6. Tap the Try the new Jetpack app button
7. Expect it to work as before, with no functional regression

Previews

Before - Big Fonts	After - Big Fonts	After - Default Fonts

Regression Notes

1. Potential unintended areas of impact
   Try Jetpack button without big fonts - on landscape & portrait.

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 - 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.
