Add Set Theory section to vim-digraphs cheatsheet (#2186 )

## Summary
- Added a new Set Theory section to the vim-digraphs cheatsheet
- Includes commonly used mathematical symbols for set theory operations
- Follows the existing format and style of the cheatsheet

## Changes
- Added Set Theory section with symbols for:
  - ∀ (forall) - `FA`
  - ∃ (exists) - `TE`
  - ∈ (element of) - `(-`
  - ∅ (empty set) - `/0`
  - ⊆ (subset or equal) - `(_`
  - ⊇ (superset or equal) - `)_`
  - ∩ (intersection) - `(U`
  - ∪ (union) - `)U`
  - ⊂ (subset) - `(C`
  - ⊃ (superset) - `)C`
- Removed duplicate set theory symbols from Math section
- Added descriptive labels for each symbol

## Test plan
- [x] Verified all digraph codes work in Vim
- [x] Checked formatting consistency with existing sections
- [x] Ensured no duplicate symbols across sections
