Fix benchmark script replacing internal package imports (#1042)

* Fix benchmark script replacing internal package imports

The sed command in bench() was replacing all occurrences of the go-toml
module path, including sub-package imports like internal/assert. This
caused the BurntSushi/toml benchmark to fail because it tried to import
github.com/BurntSushi/toml/internal/assert which doesn't exist.

Fix by anchoring the sed pattern to only match the import path when
followed by a closing quote, preserving internal package imports.

Also add a guard in the benchstathtml Python script to give a clear
error instead of an IndexError when no benchmark results are available.
