[WIP] Replaced the deprecated dep @types/blob-util

[nikopetr]

• Closes <Replace dep @types/blob-util (it's deprecated) #6001>

Additional details

Replaced @types/blob-util dependency. This is a stub types definition. blob-util provides its own type definitions, so you do not need this included.

PR Tasks

• Have API changes been updated in the type definitions?

PR Review Checklist

If any of the following requirements can't be met, leave a comment in the review selecting 'Request changes', otherwise 'Approve'.

User Experience

• The feature/bugfix is self-documenting from within the product.
• The change provides the end user with a way to fix their problem (no dead ends).

Functionality

• The code works and performs its intended function with the correct logic.
• Performance has been factored in (for example, the code cleans up after itself to not cause memory leaks).
• The code guards against edge cases and invalid input and has tests to cover it.

Maintainability

• The code is readable (too many nested 'if's are a bad sign).
• Names used for variables, methods, etc, clearly describe their function.
• The code is easy to understood and there are relevant comments explaining.
• New algorithms are documented in the code with link(s) to external docs (flowcharts, w3c, chrome, firefox).
• There are comments containing link(s) to the addressed issue (in tests and code).

Quality

• The change does not reimplement code.
• There's not a module from the ecosystem that should be used instead.
• There is no redundant or duplicate code.
• There are no irrelevant comments left in the code.
• Tests are testing the code’s intended functionality in the best way possible.

Internal

• The original issue has been tagged with a release in ZenHub.

@nikopetr Will you be able to fix the failing tests? This PR will be closed due to inactivity otherwise.

[sainthkh]

@nikopetr @jennifer-shehane If you don't mind, how about fixing this #5780? All I need to do is remove @types in front of blob-utils.

[nikopetr]

Go for it if you want to!

[sainthkh]

It's a breaking change. Check why here

[jennifer-shehane]

Rebasing this PR against cypress-4.0 branch since this will be a breaking change. Please address any merge conflicts and update the code to account for the return of a Blob object instead of a Promise.

[sainthkh]

I'll fix this when #5780 is done. Maybe I need to open a new PR, though.

[sainthkh]

NOTE: https://docs.cypress.io/api/utilities/blob.html should be fixed together.

[jennifer-shehane]

Rebasing against 5.0 branch since this will not make it into 4.0

[jennifer-shehane]

Closing due to inactivity. Please reopen a new PR - against the 5.0 branch since this will be a breaking change that fully addresses the change although I think #5780 may address some of this.
