Fix toml value ser after update of toml dependency

Update in v0.8.5 required changes to serialization code;
toml::to_string() now serializes TOML documents, not values.

This commit replaces all occurances with toml::Value serializations.

Fixes: 8fff7401 ("Update yanked zerocopy dependency")
Closes: #429
