Replace yq with pure bash for TOML parsing (#4171)

* Replace yq with pure bash for TOML parsing

The yq-based parsing only worked with jq/yq v3 and broke with go-yq v4.
This change removes the yq and uses bash for parsing. Some additional improvments:
- Handles single and double quoted values
- Strips inline comments (e.g. "#hex" #comment)

* Remove the no-longer-needed yq packages
