Use an alternative YAML library

[bfabio]

https://github.com/go-yaml/yaml seems almost abandoned, we should investigate for an alternative.

In general, there are several places in the code where we needed to workaround the lack of features of the library with subpar solutions, fe. the code that tries to figure out where in the file, in terms of line and column numbers, an errors is.

This can be an opportunity to solve those cases as well.

I suggest goccy/go-yaml. It supersedes go-yaml/yaml.

@ezatti sweet, that's exactly what it's needed!

• YAML is often used for configuration, and it is common to include validation along with it. However, the errors in go-yaml/yaml are not intuitive, and it is difficult to provide meaningful validation errors
  [...]
• Reversible transformation without using the AST for YAML that includes Anchors, Aliases, and Comments
• An API structure that allows the use of not only Encoder/Decoder but also Tokenizer and Parser functionalities.

And

• Pretty format for error notifications

is cool.

It also integrates go-playground/validator, which we are currently using anyway.
