Replace OrderedDict to dict

[serhii73]

Makes sense wherever it does not affect external APIs.
e.g. if a function uses OrderedDict internally, then yes; if a function returns OrderedDict, we probably should follow a deprecation approach, e.g. deprecate that function (but keep it for a time) and provide a new one that returns a dict.

Hey, if no one is working on this issue, I would like to work on it.

Could you also specify whether this change needs to be done throughout the code repository or in a particular directory?

Hi @PurviChaurasia
As far as I know, no one is working on this task. I think it makes sense to check the whole repository.
