.platform/services.yaml: Update generate-solr-config.sh path and Solr version

Question	Answer
JIRA issue	N/A
Type	improvement
Target Ibexa version	v4.4, v4.5, probably all v4.x
BC breaks	no

• The documenting comment about enabling Solr on Ibexa Cloud refers to old ezsystems/ezplatform-solr-search-engine instead of newer ibexa/solr. The path led to a non-existent script.
• vendor/ibexa/solr/bin/generate-solr-config.sh targets Solr 8.11.1 by default

Checklist:

• Provided PR description.
• Tested the solution manually. (Tested on Ibexa Cloud running Ibexa DXP v4.4.0 Experience and v4.4.2 Commerce)
• Provided automated test coverage.
• Checked that target branch is set correctly (main for features, the oldest supported for bugs).
• Ran PHP CS Fixer for new PHP code (use $ composer fix-cs).
• Asked for a review (ping @ibexa/engineering).

The problem exist on previous v4.

https://github.com/ibexa/post-install/blob/4.4/resources/platformsh/common/4.4.x-dev/.platform/services.yaml#L56
The path is the old one to a now non-exitent file. The mainconfig is still configsets/solr6 which is inconsistent with the use of solr:7.7 image or generate-solr-config.sh generating for Solr 8.11.1 by default.

Q: The Commerce edition has Solr enabled by default (with the configsets commited), should it be updated as well?

See:
https://github.com/ibexa/post-install/blob/main/resources/platformsh/ibexa-commerce/4.5.x-dev/.platform/services.yaml#L54-L73

I tested these changes on the experience edition on platform.sh - it works fine.
Now, I am waiting for information about commerce to continue testing.

@mnocon @katarzynazawada I would say "yes" but didn't find the time to properly test it yet.

@mnocon @katarzynazawada
I found the time to test on P.sh with a 4.4.2 Commerce and it works for me.

@adriendupuis Rebase is needed here.

[katarzynazawada]

@adriendupuis I tested a case for commerce edition but without generating the config, as on commerce solr is enabled by default. It failed with error 



- services: Error loading file: while loading repository data
        'configsets/solr8' doesn't exist in the repository
          in ".platform/services.yaml", line 65, column 25



The paths have been changed from solr6 to solr8 but the config files stayed the same.

If you generate vendor/ibexa/solr/bin/generate-solr-config.sh before deploying commerce, a good config will be generated (to the solr8 directory) and it should work.

@adriendupuis Could you please address @katarzynazawada comments (and resolve conflicts) ?

This PR kind of duplicate #28 but with more progress.

All changes should be contained in 4.6.x-dev directories. We do not modify 4.6 dirs manually, I synchronize them before releases.
