Updates to php library dependencies

[joelit]

Reasons for creating this PR

Library dependencies need to be inspected periodically to keep the PHP codebase up-to-date

Description of the changes in this PR

Changes to composer.json. The changes can be implemented by running php composer.phar update. Remaining work can be inspected by running php composer.phar outdated. Possible vulnerabilitiy reports can be inspected by running php composer.phar audit.

• phpUnit tests pass locally with my changes
• I have added tests that show that the new code works, or tests are not relevant for this PR (e.g. only HTML/CSS changes)
• The PR doesn't reduce accessibility of the front-end code (e.g. tab focus, scaling to different resolutions, use of .sr-only class, color contrast)
• The PR doesn't introduce unintended code changes (e.g. empty lines or useless reindentation)

PHPUnit now shows these warnings:

There were 6 warnings:

1) ConceptPropertyValueLiteralTest::testGetLabelThatIsABrokenDate
Expecting E_WARNING and E_USER_WARNING is deprecated and will no longer be possible in PHPUnit 10.

2) ConceptTest::testGetTimestampInvalidWarning
Expecting E_ERROR and E_USER_ERROR is deprecated and will no longer be possible in PHPUnit 10.

3) VocabularyConfigTest::testGetDefaultLanguageWhenNotSet
Expecting E_ERROR and E_USER_ERROR is deprecated and will no longer be possible in PHPUnit 10.

4) VocabularyConfigTest::testGetDataURLsNotGuessable
Expecting E_WARNING and E_USER_WARNING is deprecated and will no longer be possible in PHPUnit 10.

5) VocabularyConfigTest::testGetDataURLsMarcNotDefined
Expecting E_WARNING and E_USER_WARNING is deprecated and will no longer be possible in PHPUnit 10.

6) VocabularyConfigTest::testGetPropertyOrderUnknown
Expecting E_WARNING and E_USER_WARNING is deprecated and will no longer be possible in PHPUnit 10.

This can also be seen in the CI runs, e.g. this one.

I think these should be fixed in this PR. It would make future PHPUnit upgrades easier...

I tested this locally and also looked at the changelogs for the upgraded components. I'm a little uneasy about upgrading symfony/translation-contracts, but it seems to work, so I'm fine with that.

I think the PHPUnit warnings should be fixed (see above comment), otherwise good to merge!
