translation:update command not generating/updating ICU variant

[timosmit]

Symfony version(s) affected: 5.0.3 - 5.0.7

Description
As per my comment on #34713:

Even though I have the PHP intl extension installed, the command refuses to output the messages in the ICU format.

How to reproduce
Using the tools listed below, start a project and add translation keys (e.g. in a form or directly in a template) and run the translation:update command.

Additional context
Here's what I'm currently using:

• Windows 10
• PHP 7.4.2
• symfony/intl 5.0.7
• symfony/translation 5.0.7

Hi!
I have similar issue on Symfony 5.0.7.

Command translation:update generates file with +intl-icu on new locale, but won't update existing location.
Instead of updating existing +intl-icu file - command create new file, without +intl-icu suffix.

@timosmit can you please confirm same behaviour?

My versions:

• PHP 7.2 (mac)
• symfony/intl 5.0.7
• symfony/translation 5.0.7

@artemoliynyk I can confirm this.
