Edit Windows.yml to fix join param issue

With the current implementation the two lists are joined and become one string instead of a list of strings. This causes the final join to put a whitespace char between EACH char of the params instead of each list member.

some info replaced with asterisks but you get the gist. TASK [azdevops_agent : Debug az_devops_agent_package_params] ***************************************************************************************************************************************************************************************************************************************************ok: [****] => { "msg": "az_devops_agent_package_params: [ ' / D i r e c t o r y : E : / a g e n t ' , ' / U r l : **** , ' / T o k e n : ****' , ' / A u t h : P A T ' , ' / P o o l : D e f a u l t ' , ' / W o r k : _ w o r k ' , ' / L o g o n A c c o u n t : **** ' , ' / L o g o n P a s s w o r d : ****' ] + [ ' / E n v i r o n m e n t ' , ' / E n v i r o n m e n t N a m e : B u i l d a g e n t s ' , ' / A g e n t N a m e : **** ' , ' / P r o j e c t N a m e : ****** ' ]" }

The suggested change joins the list members correctly.
