There is a sequence of numbers: $a_{1}$, $a_{2}$, $a_{3}$, $a_{4}$, $\ldots$, $a_{n-1}$, $a_{n}$ (where $n$ is a positive integer). It is given that $a_{1}=2$, $a_{2}-a_{1}=4$, $a_{3}-a_{2}=6$, ..., $a_{n}-a_{n-1}=2n$ ($n\geqslant 2$). Find the value of $\frac{1}{a_{2}}+\frac{1}{a_{3}}+\frac{1}{a_{4}}+…+\frac{1}{a_{2023}}$.
