chore: Align snapshots in jest-matcher-utils

[pedrottimark]

Summary

Display colors concisely and clearly so you can review future changes quickly and confidently

Test plan

• index.test.ts replace 2 toMatchSnapshot assertions with toBe and more precise criterion
• index.test.ts.snap update 11 which are from toThrowErrorMatchingSnapshot assertions
• printDiffOrStringify.test.ts.snap update 6

[pedrottimark]

@jeysal Continuing our discussion from #8959 what do you think about this method to serialize aligned snapshots of diffs and reports when matcher fails:

import convertAnsi1 from '../../../pretty-format/src/plugins/ConvertAnsi1';

expect.addSnapshotSerializer(convertAnsi1);

• snapshots in expect package can use this method in separate pull request
• snapshots in jest-snapshot will need own serializer for colors in future pull request
• snapshots of generic CLI output can continue to use the original ConvertAnsi plugin
