📝 Provide a description of the improvement

The current implementation of the EMOJI_SUPPORT_LEVEL definition assumes that there are only two supported emoji version on a user machine:

1. 16
2. 15

Older operation systems like Windows 10 do not seem to support emoji 15, while they still can render some symbols (see #17988 and the related Slack thread)

Let's extend the EMOJI_SUPPORT_LEVEL definition by introducing more emojis in a particular Unicode version.

Our database CDN includes the following versions:

[
    16,
    15.1,
    15,
    14,
    13.1,
    13,
    12.1,
    12,
    11,
    5,
    4,
    3,
    2,
    1,
    0.7,
    0.6
]

Definition of Done

• Minor within the same major can be merged into a single version, like we do with 15 and 15.1.
• The map includes each version and an example emoji introduced in a particular version.
• Find usage of the EMOJI_SUPPORT_LEVEL variable and consider simplifying the algorithm.
• Verify results on different machines. Screenshots are welcome.
  • VirtualBox could be helpful.
