Clarify the docs regarding libcurl for installation on openSUSE (#2169)

- Explicitly mention the conflict error and the solution.

- Make the command that looks for libcurl more precise, since the goal is to find the specific package that places the lib in the place where the RHEL PS package looks for it.

-> **Note:** When installing PowerShell Core, OpenSUSE may report that nothing provides `libcurl`.
-`libcurl` should already be installed on supported versions of OpenSUSE.
-Run `zypper search libcurl` to confirm.
-The error will present 2 'solutions'. Choose 'Solution 2' to continue installing PowerShell Core.

+> In this case, verify that a compatible `libcurl` library is present by checking that the following command shows the `libcurl4` package as installed:
+>
+> ```sh
+> zypper search --file-list --match-exact '/usr/lib64/libcurl.so.4'
