Bumps Shouldly from 3.0.2 to 4.0.0.

Release notes

Sourced from Shouldly's releases.

v4.0.0

This is the first stable release in over 2 years. It is essentially an effort to reboot the project to being better supported and to have a regular release cadence.

See the v4 milestone for the list of changes. Although note that some changes have been done without associated issues or PR.

Where possible ObsoleteAttributes have been applied with directions on using the new API.

There is a work -in-progress v3 to v4 upgrade guide. Please feel free to help out by adding any additional notes to it.

v4.0.0-beta2

• #564 - #550 Add diffing support for Windows VS Code contributed by Eubert Go (ber2go)
• #560 - Refactor ShouldThrowAsync for cancellation handing and add test contributed by Adam Hathcock (adamhathcock)
• #555 - Fix in the Should.ThrowAsync error messages and exception handling contributed by Gabriel Milani (gmilani)
• #550 - Add diffing support for VS Code
• #411 - Object Graph Comparison - ShouldBeEquivalentTo(...) contributed by RJ Hollberg (TaffarelJr)

This release also includes the initial release of the new ShouldBeEquivalentTo method used for object graph comparison. This feature is still early in the making so I imagine there'll be a few bugs, for this reason this package will stay as a beta whilst we iterate on it.

Please raise any issues you find on our GitHub repository.

v4.0.0-beta1

• #547 - Make ShouldMatchApproved cross-platform contributed by Joseph Woodward (JosephWoodward)
• #516 - Add new Do Not Launch Strategy contributed by Brian Dukes (bdukes)
