Slightly misaligned icons in user menu

[mvarblow]

Describe the bug

Most of the standard user menu items include icons that are tagged with the "fixed width" (fa-fw) font awesome class which allows them to align nicely in the drop-down menu. However, a few are missing the fa-fw class so they appear a bit askew.
 

Orchard Core version

1.8.3

To Reproduce

Steps to reproduce the behavior:

1. Sign in to the admin dashboard
2. Enable the "Users Change Email" feature and then under Security > Settings > User Change email, check "Allow the users to change their email" setting and press Save. (This just makes the problem a bit more obvious.)
3. Click on the user icon and notice that the drop-down menu text is not aligned quite right.

Expected behavior

The menu should have nicely aligned icons and text. The problem is a bit subtle but it's enough that it gives just a bit of a sloppy appearance that some users (and our UX team) have noted.

Logs and screenshots

Here's a screenshot showing the menu with a straight red line added to help clarify that the text is not properly aligned.

Notice that most of the UserMenuItem-*.cshml templates use the fa-fw (fontawesome fixed width class) to ensure that the text after the icon will be aligned correctly. For example, the Change Email shape:

<li>
    <a class="dropdown-item" asp-route-area="@UserConstants.Features.Users" asp-controller="ChangeEmail" asp-action="Index">
        <i class="fa-solid fa-envelope fa-fw" aria-hidden="true"></i> @T["Change Email"]
    </a>
</li>

However, some of them are missing the fa-fw class. For example, the Sign Out shape:

<li>
    <a class="dropdown-item" asp-area="@UserConstants.Features.Users" asp-controller="Account" asp-action="ChangePassword" asp-route-returnUrl="@FullRequestPath">
        <i class="fa-solid fa-key" aria-hidden="true"></i> @T["Change password"]
    </a>
</li>
<li>
    <form asp-route-area="@UserConstants.Features.Users" asp-controller="Account" asp-action="LogOff" method="post" class="no-multisubmit">
        <button type="submit" class="dropdown-item">
            <i class="fa-solid fa-sign-out-alt" aria-hidden="true"></i> @T["Log off"]
        </button>
    </form>
</li>

If I add the missing fa-fw classes, then the problem is resolved.
