Update Snapshot Guide Link

Update Jest Snapshot Guide Link

Updates the snapshot guide link at the top of every .snap file from the legacy https://goo.gl/fbAQLP to https://jestjs.io/docs/snapshot-testing. Jest v30 errors out at test setup time if it sees the old link, so existing snapshot files need to be rewritten before tests can run. Read more at the Jest v30 migration notes.

Examples

Before

// Jest Snapshot v1, https://goo.gl/fbAQLP

exports[`renders correctly 1`] = `"hello"`;

After

// Jest Snapshot v1, https://jestjs.io/docs/snapshot-testing

exports[`renders correctly 1`] = `"hello"`;
