fix(ci): resolve signed-by key conflict in mssql-tools install

GitHub Actions runners have a pre-existing /etc/apt/sources.list.d/microsoft-prod.list
that references signed-by=/usr/share/keyrings/microsoft-prod.gpg. Adding the same repo
without signed-by causes a conflicting values error. Fix by removing the pre-existing
source list, using gpg --dearmor, and adding signed-by consistently.
