Add 4 new Keyboard/UI Symbols

[TimurGerasimov250]

Add U+2380-U+2383.
They are ⎀⎁⎂⎃. In Miscellaneous Technical block. Like I did #2935, it's nice to have another request, this one.
⎀: U+2380: Insertion Symbol
⎁: U+2381: Continuous Underline Symbol
⎂: U+2382: Discontinuous Underline Symbol
⎃: U+2383: Emphasis Symbol
These symbols are present in DejaVu Sans Mono, and they add a nice touch as friendly, useful keyboard/UI indicators. Iosevka already includes many keyboard/UI symbols, so these would be a great enhancement! I really love how they look! 😉
Interestingly, Inter includes the ⎀ symbol already.
They are simple with code, just combining the letter "a" with something else to look like actual characters.
Thanks! Consider them in the next update. Add them to the font as soon as all 4 mentioned are ready for inclusion and close the issue right away. Make them with code, and refine the forms after.
Thanks, be5invis.

what are they used for in practice?

[TimurGerasimov250]

Real World Use:
⎀ (U+2380) Insertion Symbol: Commonly used in editing and proofreading to indicate where text should be inserted. It corresponds to the "Insert" key on many keyboards.

⎁ (U+2381) Continuous Underline Symbol: Represents continuous underlining in text, useful in UI or documentation to show text emphasized with an unbroken underline.

⎂ (U+2382) Discontinuous Underline Symbol: Shows a dashed or broken underline, indicating emphasis or a special highlight with intermittent underlining.

⎃ (U+2383) Emphasis Symbol: Used to mark emphasis in text, often found in typographic or editorial systems to highlight important portions.
