lovelace-mushroom: [Bug]: HVAC mode icons missing on Climate cards after 3.4.0 update

Requirements

• I checked the troubleshooting section in the README to verify that I have the latest Mushroom version.
• I did a search to see if there is a similar issue or if a pull request is open.

Current Behavior

After an update to Mushroom Cards v 3.4.0, Issue persists in 3.4.1. I am observing that icons for HVAC mode selection in the Mushroom climate card are no longer visible. See attached screenshot.

This seems similar to #1359 but I am already running HA 2024.1.6, and it is not restricted to a particular device. Reproduced in Mozilla Firefox, Google Chrome, and IOS Companion App. Reverting Mushroom js files and refreshing the browser restores the icons.

Expected Behavior

HVAC Modes are shown with appropriate icons.

Steps To Reproduce

1. Update Mushroom card > 3.4.0 using HACS add-on
2. Refresh browser
3. Observe that HVAC mode icons have disappeared

Context

Lovelace configuration for a climate card:

type: custom:mushroom-climate-card
entity: climate.living_room
show_temperature_control: true
hvac_modes:
  - heat
  - cool
  - 'off'
tap_action:
  action: more-info

Environment

- Browser: Firefox, Chrome, and iOS companion app
- HA Version: 2024.1.6
- Mushroom: 3.4.1

Anything else?
