Subject: [PATCH] kata: pin indexmap crate version to 1.8

indexmap is a dependency crate of serde_ymal, which only loosely
specifies the major release version of indexmap. indexmap > 1.9.0
requires a newer version of Cargo (> 1.56.0-nightly). We can pin
the indexmap version to avoid updating the Cargo toolchain.
