Rebuild with ICU 70.1

[Shivam Mathur]

Homebrew has updated the icu4c formula to 70.1 and subsequently all php formulae in this tap have been rebuilt with it.

To upgrade, please reinstall icu4c and the php formula for the version you use.

For example to upgrade php 8.0:

brew update
brew reinstall icu4c shivammathur/php/php@8.0

Restart your terminal and verify the PHP version and ICU version

php -v
php -i | grep "ICU version"

At last, restart your webserver.
