fix(net-stubbing): match cy.intercept(url) globs against url+path

[flotwig]

• Closes intercept()'s minimatch glob-matching against routeMatcher url property no longer works #9379
• Closes Replacing cy.route with cy.intercept, having trouble with wildcard use #14256

User facing changelog

Additional details

• adds a matchUrlAgainstPath property to RouteMatcher
  • allows differentiating cy.intercept(url) from cy.intercept({ url }) or cy.intercept({ path })
  • also follows old cy.route behavior by applying a / prefix to un-prefixed url values that are being matched against a path - old behavior:

    cypress/packages/driver/src/cypress/server.js

    Lines 296 to 301 in ad194de

    	// be nice to our users and prepend
    	// pattern with "/" if it doesnt have one
    	// and str does
    	if (pattern[0] !== '/' && str[0] === '/') {
    	pattern = `/${pattern}`
    	}

How has the user experience changed?

now works as described in #9379 (comment)

Can you add a test for passing matchUrlAgainstPath: false to ensure this will strictly match against the url if set to false?

Should be good to merge after my comments are addressed.
