+vterm/here buffers no longer part of workspace buffer lists

### What did you expect to happen?

When I open a project (`projectile-switch-to-project`) and an initial file or directory in that project, then open a `SPC o T` (`+vterm/here`), I would expect the vterm buffer to be part of that project's list e.g. `+vertico|+ivy/switch-workspace-buffers`

### What actually happened?

The vterm buffer does not show in a `+vertico|+ivy/switch-workspace-buffers` list.

Interestingly:
1. vterm popups (`SPC o t`) do appear immediately in the project list.
2. you can use full Emacs session buffer lists e.g. `consult-buffer` to "bring the missing vterm buffer" into the project i.e. it subsequently shows in the `+vertico|+ivy/switch-workspace-buffers` lists afterwards.

### Describe your attempts to resolve the issue

_No response_

### Steps to reproduce

1. Open a project and initial file / folder
2. Then open a full `+vterm/here`. This vterm buffer will now take the frame, but it is not part of the workspace buffer lists.
