[15u] RFR 8265860: Update version .jcheck/conf in jdk15u to be 15.0.4

[Yuri Nesterenko]

Hi,

this is again, a change of a per repository config stored in the Git repository itself,
a minor inconvenience in two-repo setup. This .jcheck/conf file contains a value for the current
version which should correspond to the version of the fixes coming from the team repository.
To minimize merging, it is prudent to change the value as the last act of a release.
No PR since the change goes directly to the master repo.

The repository is just created, so .jcheck/conf will be a copy of that in the team jdk15u-dev,
see below.

Thanks,
--yan
