chore: replace _.entries, _.entriesIn and _.toPairs with Object.entries

[pgrzesik]

Replace _.entries, _.entriesIn and _.toPairs with Object.entries to reduce lodash usage.

Note about toPairs: I decided to not split it into multiple PRs as toPairs in lodash has the same functionality as entries.

Note about entriesIn: There was only one instance of it and I didn't notice any use/reliance on prototypal inheritance for tags so I think it's safe to replace it with Object.entries as the only difference is in it not including inherited properties.
