[Update] Replace serde_yaml

[anistark]

serde_yaml is deprecated. Need to replace with a relevant crate that's relatively active and maintained.

Add in comments which library crate you feel we should replace with.

Discussion on this on Reddit.

According to the discussion, we probably won't need to replace till new yaml specs come out. Thoughts @farhaanbukhsh ?

@anistark I agree, we should either maintain it or write a new one. Else let's use it for now.

Cool. Can revisit it when new yaml specs are out to write a new one or port again. Should we close this issue for now?

@anistark let's keep it open.
