[chore] Fixes invalid semantic error

[theBeginner86]

Notes for Reviewers

Currently, when a new meshmap snapshot workflow is added, then it replaces ph_filePath with <file-path>.
Now the issue is that ${{ inputs.fileName == '' && $ph_filePath || inputs.fileName }} resolves to ${{ inputs.fileName == '' && <file-path> || inputs.fileName }} which is semantically incorrect as <file-path> is treated as variable instead of a string.

So, this PR updates the template workflow file to ensure on replacement the line resolves to ${{ inputs.fileName == '' && '<file-path>' || inputs.fileName }}.

This would also fix: https://github.com/meshery/meshery/actions/runs/7268615022

Unfortunately, this means that anyone who has installed the MeshMap Snapshot action needs to update their workflow.

Ideally, this never exposed in the workflow. Ideally, this is controlled through user selection / configuration in Cloud.

Acceptance of this fix seems appropriate, while we prudently acknowledge and open an issue to document the need for a shift away from the location in which users configure this setting. Entirely too static here and too dependent upon GitHub Action versions.
