Update windows installer to allow user change the install path

[IndrekV]

💻 Environment

Platform: Windows

📒 Description

Update the installer so that the user can select the path they want for the application installation. We also need to test if the update after that installs to the correct location.

There are currently 2 different installer configuration files (.nsi files in branding/windows): regular and enterprise. The enterprise version should have this functionality but we need to double check it works properly.

There should be a screen that allows choosing:

• Install for all accounts (needs admin rights and allows choosing whatever location)
• Install for this user (installs to user directory, does not allow changing location)

Closes #2331

How's progress looking for this? xP Pretty weird onboarding having the app trying to install to my C drive even though it's full and then not allowing me to switch path to D: drive... ping @IndrekV @skel35

I would like to see this functionality too, really surprised there is a "browse" button but greyed out.
