[BUG] pip install does not select the right package versions

[rgeneaux]

Describe the bug

Hello,

I noticed that when doing pip install pymodaq==5.1.*, the 5.2.* version for pymodaq_gui, _data and _utils got installed. Same thing when specifying 5.1.0 or 5.1.12

Expected Behavior

pip install pymodaq==5.1.* installs all 5.1.* versions for the subpackages

this is because we didn't restrict the version of those to be below 5.2 in the 5.1.x version. Should we?

fixed in #1082
