No it doesn’t.

Reviewing other people’s PR is a collaborative task, fixing bugs "reported by others" is a collaborative work, updating docs and release notes for "other" stakeholder's consumption is collaborative work.

Unless you're building a house deep in the woods for you by you, you're collaborating with other people on different levels.

Let's be honest, introversion is a gradient scale, maybe we've shifted a bit more towards cutting out the office Watercooler talks but everything we do as a species is still highly collaborative.
