docs: matcher api reference page uses incorrect object syntax

[janaiscoding]

Context

Closes #1976
I would like to improve the website docs as per the contributing guide's website proofreading line.

Analysis

It's important that the documentation is consistent and correct, which is why I would like to add these small fixes to the typos

Solution

Removed the incorrect ; from the following lines:
const arrayMatcher: Matcher = [new Date(2019, 1, 2);, new Date(2019, 1, 4)];
const afterMatcher: DateAfter = { after: new Date(2019, 1, 2); };
const beforeMatcher: DateBefore = { before: new Date(2019, 1, 2); };
const rangeMatcher: DateRange = { from: new Date(2019, 1, 2);, to: new Date(2019, 1, 5) };
on the Type alias: Matcher API reference documentation
