text: Title: [Docs] Remove redundant provision of `id` in docs examples
  Body: We still have some examples where an `id` is provided to a component even though it is not required.
  
  1. Look through the code examples in our docs e.g. `vizro-core/docs` and `vizro-ai/docs`
  2. Remove the `id` from `vm.Graph`, `vm.Table`, `vm.AgGrid` or `vm.Card` if **it is not required**
  
  #### When is it not required?
  The `id` is normally not required if that component is not the target of any kind of action e.g. filter_interaction, export, filters or parameters. A good rule of thumb is, if the `id` appears only once in the entire app configuration, it's probably not required.
  
  **Example of a redundant `id` provision** (and the first example where you can remove it from the docs):
  
  In the first example the `id="scatter_chart"` is not required, because the Graph is not being targeted by any action. Also the `id` only appears once in the entire app configuration. In the second example it is required though, because it is now the target of the Filter.
  
  ```
  from vizro import Vizro
  import vizro.plotly.express as px
  import vizro.models as vm
  
  iris = px.data.iris()
  
  page = vm.Page(
      title="My first page",
      components=[
          vm.Graph(id="scatter_chart", figure=px.scatter(iris, x="sepal_length", y="petal_width", color="species")),
      ],
  )
  
  dashboard = vm.Dashboard(pages=[page])
  Vizro().build(dashboard).run()
  ```
  
  
  **Example where the `id` is required:**
  
  ```
  from vizro import Vizro
  import vizro.plotly.express as px
  import vizro.models as vm
  
  iris = px.data.iris()
  
  page = vm.Page(
      title="My first page",
      components=[
          vm.Graph(id="scatter_chart", figure=px.scatter(iris, x="sepal_length", y="petal_width", color="species")),
          vm.Graph(id="scatter_chart2", figure=px.scatter(iris, x="petal_length", y="sepal_width", color="species")),
      ],
      controls=[
          vm.Filter(column="petal_length",targets=["scatter_chart"],selector=vm.RangeSlider(step=1)),
      ],
  )
  
  dashboard = vm.Dashboard(pages=[page])
  Vizro().build(dashboard).run()
  ```
