docs(meter): let meter use its rootclass in storybook

[jawinn]

Description

An update to the meter component storybook templates to help with simplifying the comparison between rootClass values in #3129. The Meter component was the only component using a rootClass arg value that is not unique and its own (previously it was using spectrum-ProgressBar).

Details

Meter's Storybook template was using the rootClass for progress bar, rather than its own rootClass. It was set up this way because of the way the two components are housed together, and meter primarily just uses ProgressBar, with some added classes.

This value not being unique made it difficult to compare and match up the value of rootClass in the package.json spectrum data to the actual rootClass defined in the story files default args.

How and where has this been tested?

Please tag yourself on the tests you've marked complete to confirm the tests have been run by someone other than the author.

Validation steps

• Meter still displays correctly
• The static color background color option still works in meter; the class spectrum-Meter--staticWhite gets applied to the component root and the teal background still appears.

Regression testing

Validate:

1. The documentation pages for at least two other components are still loading, including:

• The pages render correctly, are accessible, and are responsive.

2. If components have been modified, VRTs have been run on this branch:

• VRTs have been run and looked at.
• Any VRT changes have been accepted (by reviewer and/or PR author), or there are no changes.

To-do list

• I have read the contribution guidelines.
• If my change impacts other components, I have tested to make sure they don't break.
• ✨ This pull request is ready to merge. ✨
