PARAM_GENERATION seems deprecated

@ArnauPrat I was maintaining the https://github.com/ldbc/ldbc_snb_datagen/wiki/Configuration wikipage that says:

• PARAM_GENERATION: indicates whether the parameters for SNB queries are generated. You should only use it with standard scaleFactor (e.g., SF 1). Always disable PARAM_GENERATION when using the data generator for non-standard input parameters (e.g., when you set numYears instead of using scaleFactor).

However, I cannot find any instances of the PARAM_GENERATION string across LDBC projects.

It was removed in commit 2b30303, and the last release where it was available was v0.2.5. It was then reintroduced in the Java code (and not the run.sh shell script) in 5c8e26a, which was included from the next release, v0.2.6, onwards.

I documented that it is missing in https://github.com/ldbc/ldbc_snb_datagen/wiki/Configuration/_compare/dcaf4b1e36667032bd42253d7ad74f526609693d...9863ddf9eee5d3629bc3728f69c5858e850c061c.
