fix(dict): Add suggestions "greater" and "gather" for the typo "grather"

[kachick]

Sorry, I might have written a wrongly formatted request for multiple candidates.

grather -> greater|gather

Typos now detect it as a disallowed word. I don't have confidence that this is valid or invalid because this pattern is not found for other entries.

Current

> cargo test --workspace --no-run

> echo 'grather' | ./target/debug/typos --version -
typos-cli 1.24.3

> echo 'grather' | ./target/debug/typos -
error: `grather` is disallowed
  --> -:1:1
  |
1 | grather
  | ^^^^^^^
  |

After this change

> echo 'grather' | ./target/debug/typos -
error: `grather` should be `greater`, `gather`
  --> -:1:1
  |
1 | grather
  | ^^^^^^^
