fix: set require "administrate/version"

[JohnnyKei]

We met uninitialized constant Administrate::VERSION error after v0.20.0.

How to reproduce
Remove require "administrate/version" from administrate.gemspec.

bundle exec rspec spec/controllers/admin/application_controller_spec.rb:123

Looks good to me, we are not requiring that file except in gemspec https://github.com/search?q=repo%3Athoughtbot%2Fadministrate%20version&type=code

Which version did you upgrade from? Are you doing anything with the VERSION constant?

FWIW, that line has been in there for 9 years. I'd not expect that to be a problem because of that version because of that: https://github.com/thoughtbot/administrate/blame/main/administrate.gemspec#L3

We are also facing this on this pr: chatwoot/chatwoot#8741

here is the trace

I think it throws this error when administrate renders the deprecation warnings.

mostly happening in the views where we use: https://github.com/fishbrain/administrate-field-belongs_to_search

I did update from 0.19.0 to 0.20.0.

v0.19.0...v0.20.0#diff-3c290ae4fe2e0753529c6c6dfb1ccaa391ac53237bbd0ca7de07b5f60cd68732R43

I think previous version did not use VERSION in the application code, only was used in gemspec.

The example app read from gemspec, so it may work

Ah hah, yes, that all adds up. I think this is the right way to go then.

I can't think of a good way to test this, at least with what structure we have already, so I'm not going to let that hold us back.

I've just pushed v0.20.1 which includes this fix, thanks for reporting and providing a solution!
