chore: changelog spelling

[NickyMeuleman]

I started this branch because I noticed some warnings while building eza with cargo build --release.

warning: use of deprecated associated function `chrono::NaiveDateTime::from_timestamp_opt`: use `DateTime::from_timestamp` instead
   --> src/fs/file.rs:734:24

    |                        ^^^^^^^^^^^^^^^^^^
    |
    = note: `#[warn(deprecated)]` on by default

   --> src/fs/file.rs:763:24

warning: `eza` (lib) generated 2 warnings
warning: `eza` (bin "eza") generated 2 warnings (2 duplicates)

Then I noticed I was on an old version and did a git pull

Turns out those errors were already fixed, and there was nothing to do! Except change 1 measly letter in the changelog. :sweat_smile:
