deps: restore minimum ICU version to 65
Browse files Browse the repository at this point in the history
This modifies 40df0dc so that the changes it applies are only used
if ICU 67 or greater is used, and restores the previous code path for
versions of ICU below 67.

The minimum ICU version was bumped to 67 in Node.js 14.6.0 by
#34356 but the referenced V8
commit[1] isn't on `v14.x-staging` and appears to have been reverted
on V8 8.4[2] so this PR also restores the minimum ICU version to 65.

[2] v8/v8@eeccede
