platex-dev uses the e-uptex engine

[Ulrike Fischer]

platex-dev uses a different engine than platex on my system (e-uptex
versus e-ptex):

~~~~
C:\Users\micro\Documents\Tests>platex-dev test-utf8
This is e-upTeX, Version 3.141592653-p4.1.0-u1.29-230214-2.6

C:\Users\micro\Documents\Tests>platex test-utf8
This is e-pTeX, Version 3.141592653-p4.1.0-230214-2.6 (utf8.sjis)

Is that intended??
