ui: fix configwith doctest

4.2 cannot be expressed with IEEE floating point losslessly, and could
cause test failure on some platform:

    File ".../mercurial/ui.py", line 414, in mercurial.ui.ui.configwith
    Failed example:
        u.configwith(float, s, 'float2')
    Expected:
        -4.2
    Got:
        -4.2000000000000002

This patch fixes that by changing the number to 4.25, which can be expressed
by the binary number 100.01.
