Transpose-inverse map is inner automorphism on special linear group of degree two

Statement
Let $$R$$ be any commutative unital ring and $$SL(2,R)$$ be the special linear group of  degree two over $$R$$. Then, the transpose-inverse map, restricted to $$SL(2,R)$$, is an inner automorphism, and equals conjugation by the matrix $$\begin{pmatrix} 0 & -1 \\ 1 & 0 \end{pmatrix}$$.

In other words, for any matrix $$A \in SL(2,R)$$:

$$(A^t)^{-1} = \begin{pmatrix} 0 & -1 \\ 1 & 0 \end{pmatrix} A \begin{pmatrix} 0 & -1 \\ 1 & 0 \end{pmatrix}^{-1}$$.
