gitlab-elasticsearch-indexer can't be built with Homebrew without calling `brew link icu4c --force`

Overview

On a new GDK install on an M1, I got:

% bundle exec rspec spec/lib/banzai/filter/references/issue_reference_filter_spec.rb
Run options: include {:focus=>true}

All examples were filtered out; ignoring {:focus=>true}
rake aborted!
Gitlab::TaskFailedError: # pkg-config --cflags  -- icu-i18n icu-i18n

Perhaps you should add the directory containing `icu-i18n.pc'

GitLab Elasticsearch Indexer failed to install, cleaning up tmp/tests/gitlab-elasticsearch-indexer!

An error occurred in a `before(:suite)` hook.

icu4c is installed:

% brew list icu4c | grep pc
/opt/homebrew/Cellar/icu4c/69.1/lib/pkgconfig/icu-uc.pc
/opt/homebrew/Cellar/icu4c/69.1/lib/pkgconfig/icu-io.pc
/opt/homebrew/Cellar/icu4c/69.1/lib/pkgconfig/icu-i18n.pc

I had to manually do this:

% brew link icu4c --force
Linking /opt/homebrew/Cellar/icu4c/69.1... 61 symlinks created.

If you need to have this software first in your PATH instead consider running:
  echo 'export PATH="/opt/homebrew/opt/icu4c/bin:$PATH"' >> ~/.zshrc
  echo 'export PATH="/opt/homebrew/opt/icu4c/sbin:$PATH"' >> ~/.zshrc
% pkg-config --cflags  -- icu-i18n icu-i18n
-I/opt/homebrew/Cellar/icu4c/69.1/include

Steps to replicate (optional)

Proposal (optional)

Automatically run brew link icu4c --force?
