[williamdes]

Previous update: #17112

Description:

There is no breaking changes to be expected, some versions between the two had removed PHP 7 support.
But it was added back in https://github.com/tedious/JShrink/releases/tag/v1.6.5

Review

• Functional review done
• Potential edge cases thought about (behavior of the code with strange input, with strange internal state or possible interactions with other Matomo subsystems)
• Usability review done (is anything maybe unclear or think about anything that would cause people to reach out to support)
• Security review done
• Wording review done
• Code review done
• Tests were added if useful/possible
• Reviewed for breaking changes
• Developer changelog updated if needed
• Documentation added if needed
• Existing documentation updated if needed

@williamdes If the new version is also compatible with PHP 7.2, we should update the composer.lock here, to ensure it's used for newer releases. But maybe should wait till the other PR is merged (if possible) to avoid merge conflicts..
