Make ->withHost available when using visit(..)

[negoziator]

Make withHost chainable directly on visit()

Currently withHost is not chainable directly on visit()

Added missing function withHost(..) in PendingAwaitablePage

Usage

Single visit withHost

visit('/dashboard')
    ->withHost('app.localhost')
    ->assertSee('Content from app.localhost');

Visit withHost takes precedence over global host

pest()->browser()->withHost('app.localhost');

visit('/dashboard')
    ->withHost('test.domain')
    ->assertSee('Content from test.domain');

Visit without withHost() falls back to the global host

pest()->browser()->withHost('app.localhost');

visit('/dashboard')
    ->withHost('test.domain') // <-- Only overrides host in the visit
    ->assertSee('Content from test.domain');

visit('/dashboard')
    ->assertSee('Content from app.localhost'); // <--- Falls back to global host
