`cy.type` accept keyboard shortcut syntax to release modifiers

[kuceb]

currently, in order to simulate the user pressing "ctrl+bhello world", you would need two cy.type commands if you want to simulate releasing the ctrl key after the b:

cy.get('...').type('{ctrl}b').type('hello world')

We should introduce a new syntax {<mod>+<key>} to specify you want to press-and-release the ctrl key after one (or more) key:

cy.get('...').type('{ctrl+b}hello world')

The code for this is done in cypress-io/cypress#8499, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
