Describe the bug
Incorrect file paths being logged when trying to validate .mjml files via glob

To Reproduce
Steps to reproduce the behavior:

Create a index.mjml file in a nested directory (./foo/bar/baz/index.mjml):

<%# This Source Code Form is subject to the terms of the Mozilla Public
  # License, v. 2.0. If a copy of the MPL was not distributed with this
  # file, You can obtain one at http://mozilla.org/MPL/2.0/. %>

<mj-section>
  <mj-column>
    <mj-text css-class="text-header">
      <span data-l10n-id="verifyLoginCode-title">Is this you signing up?</span>
    </mj-text>
  </mj-column>
</mj-section>

<%- include('/partials/location/index.mjml') %>

<mj-section>
  <mj-column>
    <mj-text css-class="text-body">
      <span data-l10n-id="verifyLoginCode-prompt">
        If yes, use this verification code in your registration form:
      </span>
    </mj-text>

    <mj-text css-class="code-large"><%- code %></mj-text>

    <mj-text css-class="text-body-no-margin">
      <span data-l10n-id="verifyLoginCode-expiry-notice">It expires in 5 minutes.</span>
    </mj-text>
  </mj-column>
</mj-section>

<%- include('/partials/automatedEmailChangePassword/index.mjml') %>

pwd # /tmp/mjml-validate-test
tree foo/

foo/
└── bar/
    └── baz/
        └── index.mjml

## OR
find foo -type f # foo/bar/baz/index.mjml

Now, if I run npx mjml --validate "foo/**/*.mjml" in my root directory (/tmp/mjml-validate-test), I get the following validation errors:

Line 1 of /private/tmp/mjml-validate-test/foo/bar/baz/foo/bar/baz/index.mjml (%#) — Element %# doesn't exist or is not registered
Line 13 of /private/tmp/mjml-validate-test/foo/bar/baz/foo/bar/baz/index.mjml (%-) — Element %- doesn't exist or is not registered
Line 31 of /private/tmp/mjml-validate-test/foo/bar/baz/foo/bar/baz/index.mjml (%-) — Element %- doesn't exist or is not registered

Command line error:
Validation failed

Expected behavior

/private/tmp/mjml-validate-test/foo/bar/baz/index.mjml

Actual behavior

/private/tmp/mjml-validate-test/foo/bar/baz/foo/bar/baz/index.mjml

Note how the "/foo/bar/baz/" file path part seems to be duplicated.

-/private/tmp/mjml-validate-test/foo/bar/baz/foo/bar/baz/index.mjml
+/private/tmp/mjml-validate-test/foo/bar/baz/index.mjml

MJML environment (please complete the following information):

• MJML Version: 4.12.0
• MJML tool used: CLI

npx mjml --version
# mjml-core: 4.12.0

Unfortunately, I don't know enough about mjml yet to know if <%- include('/partials/location/index.mjml') %> syntax is valid or if we're doing some pre/post processing internally, but that seems to explain these validator errors:

(%#) — Element %# doesn't exist or is not registered
(%-) — Element %- doesn't exist or is not registered
(%-) — Element %- doesn't exist or is not registered

<%- include('/partials/location/index.mjml') %> is not a MJML include (it's weird that the regexp does grab them tho)
cc @kmcb777 can you check if we didn't broke something while updating the watch ?
