feat: return entries instead of values in toJSON method

[Shiva953]

Please describe the changes this PR makes and why it should be merged:
This PR modifies the toJSON method in the collection package to return entries instead of just values. Currently, the toJSON method only returns values from the collection, which makes it impossible to create a new collection from the JSON output.

To fix this issue, this PR modifies the toJSON method to return entries instead of just values. This will preserve the keys and allow the creation of a new collection/map from the returned data. (FIXES #9310 ).
