URL Encode SMTP user & passowrd

[READ] Step 1: Are you in the right place?

Issues filed here should be about bugs for a specific extension in this repository. If you have a general question, need help debugging, or fall into some other category use one of these other channels:

• For general technical questions, post a question on StackOverflow with the firebase tag.
• For general Firebase discussion, use the firebase-talk google group.
• To file a bug against the Firebase Extensions platform, or for an issue affecting multiple extensions, please reach out to Firebase support directly.

[REQUIRED] Step 2: Describe your configuration

• Extension name: firestore-send-email
• Extension version: 0.1.10

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

Consider the following SMTPS URI: smtps://XXX:XXX/[e-mail]:465.

If passed into nodemailer / firestore-send-email configuration will result in following error when attempting to send email: getaddrinfo ENOTFOUND XXX.

To resolve an issue the password and username have to be URL encoded, which is not mentioned anywhere in the configuration description.

Expected result

There is a not-to URL encode the password and username.

Actual result

There is no such note, which results in confusing error message.

We should be able to update the extension itself to use encodeURI so that someone installing the extension doesn’t need to figure out encoding

Thanks @alfredsgenkins.

I have updated this for consideration.
