Rapidjson crash when attempting to allocate memory

[FlorentP42]

Since PR #1488 it appears that any plugin using Rapidjson will crash immediately when attempting to open any document with a similar stack trace :

Could you please rollback to a version that is not broken?

[MarkRiddoch]

Are you still seeing this issue? With the latest updates I am not seeign it for other plugins using JSON config items. If so let me know and I will pull the plugins from FledgePower and see if I can reproduce it that way.

@MarkRiddoch I have not made a new attempt with the develop version recently as I was testing on the tagged 2.5.0 version of Fledge and no longer on develop. But if there was no change on the rapidjson library of develop since two weeks ago, I doubt this may produce different results now...
Also I remember the FledgePower container produced by this pipeline was pointing to develop when getting the rapidjson sources and definitely contained the issue: https://github.com/fledge-power/fledgepower-deployment/actions/runs/11707131150/job/32605786603
Later generations are pointing to the 2.5.0 tag so we no longer experience it.
