When a user presses Enter inside a single-line TextBox within an Adaptive Card form, find the first Submit or Execute action on the card and trigger form submission with the current input values. This enables keyboard-only form workflows (e.g. login/unlock forms in extensions) without requiring users to click the submit button. Multiline text inputs (AcceptsReturn=true) are excluded so that Enter still inserts newlines in those fields. Fixes #46003 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
Adds Enter key support for submitting Adaptive Card forms in the Command Palette. When a user presses Enter inside a single-line
Input.Textfield, the form is automatically submitted using the firstAction.SubmitorAction.Executeaction on the card.Problem
When extensions use
FormContentwith Adaptive Cards, pressing Enter inside anInput.Textfield does not trigger submission. Users must click the submit button with their mouse (or tab to it), breaking keyboard-only workflows like login/unlock forms.Solution
