Subject: [PATCH] docs(forms): use a number as input value for formControlName
 (#30606)

PR #29473 changed the docs to use a string as the input value of `formControlName`, as it used to only accept a string.
This has been changed, and `formControlName` now accepts a string or a number, so the example in the docs can use a binding as they used to.

PR Close #30606
