2C "where the user can adjust the embedded control's value" is misleading

[JAWS-test]

For read-only or disabled controls, the user cannot change the value and yet the value should be used instead of the label. Therefore the insertion "where the user can adjust the embedded control's value" should be removed

Updated the title to reflect the reordering in #122

For the agenda (cc @jnurthen )

• confirm and clarify: "yet the value should be used instead of the label"

[jnurthen]

From 2021/06/03 meeting <Jory> msumner: wanted to get clarification, should the value be used instead of label

<Jory> msumner: should we remove ability to adjust embedded control value or add a note to except readonly

<Jory> jamesn: unless this list is not exhaustive, why do we need a change

<Jory> jcraig: there are examples where there is a list of radios where an option needs a secondary input, e.g. a quantity

<Jory> jamesn: feels that use is covered

<Jory> jamesn: votes we drop it, joanie agrees

<Jory> jcraig: I agree

<Jory> joanie: instead of dropping should we come up with a phrase that means has value

<Jory> msumner: will open a PR
