refactor(labware-creator): split apart sections into separate components

[shlokamin]

Overview

This PR splits the first three sections (create new definition, upload existing, and regularity) into their own components.

Each section component is responsible for getting formik values for displaying errors via useFormikContext. Each new section we make can take advantage of the function getFormAlerts that takes formik props and returns all relevant errors that should be displayed. See CreateNewDefinition and Regularity for how to use it.

New sections should also use the SectionBody UI component to format content + alerts (this was extracted from the old Section component). Again see CreateNewDefinition and Regularity for how to use it.

I was bad and did not include test coverage here (soon to come!). In future PRs breaking out sections let's please take the time to add test coverage (preferably using testing library). In the next PR I'll have a few tests to serve as an example.

Partially addresses #7707
