Isn't the Trinity based on a forged verse (1 John 5:7)?
No. The longer form of 1 John 5:7 (the "Comma Johanneum") is a late addition and modern Bibles footnote or omit it. The doctrine of the Trinity does not depend on it and never did — it rests on dozens of other passages.
In more depth
The "Johannine Comma" is the clause "...the Father, the Word, and the Holy Spirit; and these three are one" in some older editions of 1 John 5:7–8. It is almost certainly not original.
The clause is absent from every Greek manuscript before the fourteenth century, from the earliest Latin, and from the writings of the Greek fathers who argued about the Trinity for centuries. It appears to have entered the Latin tradition as a margin note that was later copied into the text, and from there into a few late Greek copies and the early printed editions behind the King James Version.
Christian theologians defended the Trinity for over a thousand years without citing it. The case is built from the baptism of Jesus, the baptismal formula of Matthew 28:19, John 1:1, the divine titles and works given to the Son and the Spirit, and Paul's benedictions. Remove the Comma entirely and the argument is untouched.
That textual criticism works: scholars identified the addition, and honest Bibles flag it. The same discipline that removes this verse is the one that vindicates the rest of the text.
