Breaking: #84744 - Raise doctrine/dbal-version

See Issue #84744

Description

The upgrade doctrine/dbal to 2.7.1 came with a potentially breaking change that makes it necessary to adjust the format of DateInterval fields.

Those fields can now be negative as well and thus are expected to begin with either + or -.

Impact

Users not having prefixes in DateInterval fields will be greeted by a ConversionException.

We do not expect many (if any) TYPO3 users to be affected by this change.

You can read up on the topic at https://github.com/doctrine/dbal/pull/2579 and https://github.com/doctrine/dbal/releases/tag/v2.7.0.

Affected Installations

Users with existing DateInterval fields that don't yet use the proper field prefix.

Migration

Manually provide the proper prefixes in your DateInterval fields.

If you didn't use negative DateIntervals yet, you can safely prefix your data with +.
