PG15 beta1 fix pg_stat_statements view document

[Shinoda, Noriyoshi (PN Japan FSIP)]

Hi hackers,

The attached patch modifies the pg_stat_statements view documentation updated 
in PostgreSQL 15 Beta 1.
The data type of the following columns in the pg_stat_statements view is bigint 
in the current document, 
but it is actually double precision.
        jit_generation_time
        jit_inlining_time
        jit_optimization_time
        jit_emission_time

Regards,
Noriyoshi Shinoda
