Foundation: Update Progress templates

[bheston]

Pull Request

📖 Description

As part of the next major release of fast-foundation, we wanted to do a complete review of the component templates and align the structure and naming as much as possible.

This PR is split from #6286 and updates the Progress and Progress Ring templates.

Before on the left, update on the right. "C" = class, "P" = part, "R" = role, "S" = slot. 💔 = potentially style-breaking.

Progress

• 💔 Rename "progress" container to "determinate" and "indeterminate"
• 💔 Change “determinate” div to slot
• 💔 Remove “indeterminateIndicator2” option

Progress ring

• 💔 Follow Progress structure

Ran the branch locally, didn't notice any issues.

Closing this as we're closing out work on foundation per #6951, and this seems like it will potentially break downstream consumers.
