Function denoPlugins

creates an array esbuild plugins that can resolve imports in the same way deno can.

it is effectively a cumulation of the following three plugins (ordered from highest resolving priority to lowest):

• importMapPlugin: provides import-map alias path-resolving for entry-points and esbuild's native resolvers (i.e. when in the default namespace).
• httpPlugin: provides http:// and https:// path-resolving and resource-fetching loader.
• jsrPlugin: provides a jsr: to https://jsr.io/ path-resolver.
• npmSpecifierPlugin: provides a resolver that strips away npm: specifier prefixes.
