chore(deps): update rollup

[BobbieGoede]

I was checking to see if updating Rollup would improve build speed 😅 I noticed a bunch of warnings while building due to the PURE comments usage, this is new in Rollup 4 https://rollupjs.org/migration/#general-changes:~:text=Last%2C%20you%20may,can%20help%20you, so likely these comments were not actually being used.

These warnings can be seen in the build step of #1578, I've listed some of them below:

Based on https://rollupjs.org/configuration-options/#pure I'm not entirely sure why the PURE comments before a [] or { [_locale]: {} } are not supposedly incorrect, strictly speaking these also invoke a constructor right?

Thanks!

I'm not entirely sure why the PURE comments before a [] or { [_locale]: {} } are not supposedly incorrect, strictly speaking these also invoke a constructor right?

These are primitive literals and constructor syntax sugar internally.
As far as I can remember, that decoration was correct in rollup v1 and v2.
In rollup v4, rollup now outputs a warning if the rollup has incorrect annotation, as in this PR. So I think it is correct to respect the rollup warning!
