Fix wrong parameter in ITRF2000 to ITRF2005 transfomations

[keyos89]

There seems to be one zero too much in the ds-parameter.

Hej Karoline, nice catch! I believe you are correct. It seems we are using those exact numbers in a test case. Please also adjust the value here:

https://github.com/OSGeo/proj.4/blob/62799e10a3aa51e61e428e87f4aec10f65c737cb/test/unit/test_io.cpp#L8676-L8684

(i think that's the only place tests needs to be adjusted).

+1 This fix also agrees with EPSG:

Yes, this was simply a typo on my part. Thanks for fixing it @keyos89!
