chore: try blobless checkout method

[jennifer-shehane]

Additional details

Adds the new method: blobless property to our checkout step in CircleCI (as opposed to the default of full. https://circleci.com/docs/reference/configuration-reference/#checkout

This essentially runs this git clone --filter=blob:none <url>

creates a blobless clone. These clones download all reachable commits and trees while fetching blobs on-demand. These clones are best for developers and build environments that span multiple builds. https://github.blog/open-source/git/get-up-to-speed-with-partial-clone-and-shallow-clone/

I'm not aware of why we would need a full clone in our case, but I may be wrong here.

Before

This is especially helpful since this operation runs on the node_modules install job, which is the gate for all subsequent jobs.

Checkout takes 24 seconds

After

Checkout takes 6 seconds

Steps to test

How has the user experience changed?

PR Tasks

• Have tests been added/updated?
• Has a PR for user-facing changes been opened in cypress-documentation?
• Have API changes been updated in the type definitions?

Note

Switches CircleCI checkout steps to blobless method in pack-workflows and node_modules_install jobs.
