build(makefile): disable two go fix modernizers that emit broken code

go fix runs the modernize suite since Go 1.26, and two of its analyzers
rewrite this codebase into code that does not compile, so make fmt broke
the build and then make lint. CONTRIBUTING tells every contributor to run
both before opening a PR.

embedlit folded telemetryCfg.LogLevel into a literal that already set that
key, and errorsastype rewrote errors.As to errors.AsType[HttpError] even
though HttpError does not embed error. Disable both, with a TODO covering
when each can come back.

+# TODO: restore a plain "go fix ./..." once both modernizers stop rewriting this

+#   embedlit folds a post-literal field assignment into a literal that already
+#   sets that key, producing a duplicate field name (cmd/gotenberg.go). Fixed in
+#   Go 1.27.1, so drop that flag once the toolchain moves past 1.27.0.
+#   See https://github.com/golang/go/issues/81101.
+#   errorsastype rewrites errors.As to errors.AsType[T] without checking that T
+#   satisfies error, which breaks on api.HttpError since it does not embed
+#   error. Still broken as of Go 1.27.1.
