Update build.gradle.kts

[NetTruyenOfficial]

Trust me, I'm the admin of this website.
I won't be using "s" anymore in the future.

Checklist:

• Updated versionCode value in build.gradle.kts
• Updated baseVersionCode in build.gradle.kts (if updated multisrc theme code)
• Referenced all related issues in the PR body (e.g. "Closes #xyz")
• Set the contentWarning configuration in build.gradle.kts appropriately
• Have not changed source names
• Have explicitly kept the id if a source's name or language were changed
• Have tested the modifications by compiling and running the extension through Android Studio
• Have removed web_hi_res_512.png when adding a new extension
• This PR is AI-assisted, I have reviewed the changes manually and confirmed they are not slop

There are so many Vietnamese sources called 'NetTruyen'. You should use 'NetTruyenS' to identify this specific source, or rename the website to something else like 'Bách Truyện' ¯_(ツ)_/¯

Marking as a draft

• Unless your website's name & icon is going to be called "NetTruyen Unofficial", the extension name should at least be "NetTruyen (unoriginal)" to fall in line with copycat sources.
• You didn't bump the versionCode, as mentioned in the PR checklist (that you falsely acknowledged).

set id in source {} block to the current source's id; otherwise users will be forced to migrate. you can find current id from the repo index
