Form elements do not announce themselves properly

[douglasbouttell-camunda]

Is your feature request related to a problem? Please describe.

When using a screenreader, form-js does not do the following:

• Announce the descriptions of any fields
• Announce the name of a group
• Announce if a field is required
• Announce if a field is invalid

Additionally, form-js will announce elements of the form which are purely visual. For example, it will announce the asterisk which denotes a required field.

Describe the solution you'd like

Add in the appropriate HTML and ARIA labels.

Describe alternatives you've considered

None

Additional context

Announces Creditor *, edit text. */"star" is a purely visual element. Does not announce that the field is required and invalid.

Voiceover does not show this field as having a description when it does visually.

Does not announce the group name on entering.
