vite: add https variables

Personal note from Rubicon: I am unware that I
originally put the localhost.direct cert files
into the repository. All reference to the files
are now removed.

Sorry for the inconvenience.

+# Set up HTTPS for the dev server
+
+With a valid HTTP server, you can let the other devices access your dev server, with features only available to HTTPS.
+
+You can use [localhost.direct](https://get.localhost.direct) certificate for set up local HTTPS server. Any vaild certificate is also allowed.
+
+Download the certs and unpack them. In this document we put them under "tools/cert/".
+
+Create or edit the file ".env.local", this file is ignored by git. Copy the content from ".env":
+
+```env
+DEV_SERVER_HTTPS_CERT_BASE=
+DEV_SERVER_HTTPS_CERT_PASS=
+```
+
+The `DEV_SERVER_HTTPS_CERT_BASE` is the basename for your cert. The cert includes two files to work: one's suffix is `.key`, the other is `.crt`. The base is the common part of them.
+
+If you have files "tools/cert/localhost.direct.key" and "tools/cert/localhost.direct.crt", the value you need is "tools/cert/localhost.direct".
+
+The `DEV_SERVER_HTTPS_CERT_PASS` is the password to unlock the key. For the localhost.direct, it's `password`.
+
+Here is an example:
+
+```env
+DEV_SERVER_HTTPS_CERT_BASE=tools/cert/localhost.direct
+DEV_SERVER_HTTPS_CERT_PASS=localhost
+```
