Bashism in snapd.sh (aka apps-in-path.sh) breaks dash

[Alvin Seville]

WSL version: 2
Kernel version: Linux version 5.4.72-microsoft-standard-WSL2 (oe-user@oe-host) (gcc version 8.2.0 (GCC))
Ubuntu version: 20.04.2 LTS

Steps to reproduce issue:
- run chsh -s /bin/sh (/bin/sh points to dash on my system)
- open new Windows Terminal tab and obtain -sh: 6: export: Files/PowerShell/7:/mnt/c/tools/ruby30/bin:/mnt/c/Python39/Scripts/:/mnt/c/Python39/:/mnt/c/WINDOWS/system32:/mnt/c/WINDOWS:/mnt/c/WINDOWS/System32/Wbem:/mnt/c/WINDOWS/System32/WindowsPowerShell/v1.0/:/mnt/c/WINDOWS/System32/OpenSSH/:/mnt/c/Program: bad variable name error

Steps to fix issue:
- replace 6-th line in /etc/profile.d/apps-bin-path.sh with export PATH="$PATH:${snap_bin_path}"

As I understood from @therealkenc response here https://github.com/microsoft/WSL/issues/6838#issuecomment-825161072 I have to fill this issue here.

The issue as pointed on the github report is that the line is currently

    export PATH=$PATH:${snap_bin_path}

without quoting it seems to not deal correctly with space in directory names?

On a second look, this is fixed by ae84b651f464f297c046b60b82c60ecdd69ce80e - a patch from the 2nd of Feb 2021.
