I installed RHEL 9.2 from the Azure Marketplace and installed git from dnf. I found that the latest git package available in the default repositories is git version 2.39.3. Since you already have git installed you can clone the latest repository and install it. These steps worked for me. You could also download the version you wanted and install it in a similar way.
sudo su
dnf install -y wget unzip tar make gcc openssl-devel libcurl-devel expat-devel zlib-devel
git clone https://github.com/git/git
cd git
make
make install
exec bash
git --version
