`organizationSwitcherPopoverActionButtonText` customization id removed

The organizationSwitcherPopoverActionButtonText customization id has been removed, as the text for this button is now directly rendered inside the button rather than an extra wrapping element. The nested ids organizationSwitcherPopoverActionButtonText__manageOrganization and organizationSwitcherPopoverActionButtonText__createOrganization have also been removed. Any styling that needs to apply to the text can be applied to its direct parent cl-organizationSwitcherPopoverActionButton.
