Let $\{a_{n}\}$ be a sequence of positive terms with a common difference. Given that $a_{3}=3$, and $a_{2}$, $a_{5}-1$, $a_{6}+2$ form a geometric sequence.<br/>$(1)$ Find the general formula for $\{a_{n}\}$;<br/>$(2)$ Let the sum of the first $n$ terms of $\{a_{n}\}$ be $S_{n}$, and define ${b_n}=\frac{1}{{{S_n}}}$. Find the sum of the first $n$ terms of the sequence $\{b_{n}\}$ denoted by $T_{n}$.
