chore(build): Update and hoist rollup-plugin-terser

[lobsterkatie]

In preparation for the new bundling process, this updates rollup-plugin-terser to latest and hoists it into the main package.json.

To see what effects this has on the resulting minified bundles (because this is terser we're talking about, there's no effect on non-minified bundles), it's easiest to think of the upgrade in stages.

First bump: 4.x -> 5.x.

Effect 1: License text in minified bundles:

This can be mitigated by enforcing the removal of comments (in the terser settings):

Effect 2: Extra parentheses. This is easiest to see in a file where each character has been put on its own line.

Second bump: 5.x -> 6.x

This results in no bundle changes

Third bump: 6.x -> 7.x

(Note: screenshots are all from bundle.min.js from @sentry/browser after it's been run through auto-formatting to make it easier for git to figure out what the actual differences are.)

Effect 1: return (x = someFunc)(args) -> return( (x = someFunc), x(args) )

Effect 2: Assigning repeated values to a variable

Effect 3: Lots of renaming of single-letter variables

Because these are all essentially cosmetic changes, this should be a safe upgrade.
