Revert "feat: [CI-18487]: Glob pattern support for PLUGIN_STRIP_PREFIX"

[fernandrone]

Reverts #196

Quoting from @silverwind on #196

This breaks existing use with relative paths like foo/ which fail with strip_prefix must start with '/'.

@Ompragash this is breaking several of our pipelines which are pulling from :latest (and likely breaking other users too).

Given the issue I'd suggest reverting this.
