BCDA-2312 Accessibility: Do not duplicate credential elements

[dhgreene]

Fixes BCDA-2312

Our nifty button to copy client ID's/secrets from the user guide has an accessibility flaw: it has a hidden duplicate input element, to make copying easier.

This PR does away with the input element, and thus the duplication, accepting the challenge goal of the ticket and sidestepping the original request (to add <label> tags for the input).

Proposed Changes

• Change the copyText() function to not need an input element

Security Implications

• new software dependencies
• security controls or supporting software altered
• new data stored or transmitted
• security checklist is completed for this change
• requires more information or team discussion to evaluate security implications

The Javascript function touches security credentials, albeit publicly published credentials. However, there is no effective change in security posture with the script changes.
