Issue:
Time component's colon not positioned correctly
### Description

When adding a time component within a Form, the colon separator is not positioned correctly. Instead of being in the middle (like in the storybook docs) it is further below.

Pull request:
fix(form): ensure that additional margin-bottom is not applied to Time component - FE-7054
When using a Time component within a Form, the separator is incorrectly positioned. This fix ensures that the height of the Time component is calculated correctly and that margin-bottom is not applied twice, thus ensuring the separator is rendered correctly in the centre position.

fixes #7164

I have created this as a non-draft PR because I needed to see if the Chromatic snapshots are as expected.

- Check that you're happy that the new Chromatic snapshot sufficiently captures what is required to avoid potential regressions in the future.
- No other styling regressions relating to Form.
