kinda goroutine leak with pgx module in awaitDone

[Olex1313]

Hello, I've been using trm for my personal projects with pgx backend and found out some edge case in trm/v2/manager.go.

Apparently, when a context with external cancel function is passed in Manager.Do, the pgx implementation of a transaction relies on context either have no Done channel or getting the cancel function from manager.

It is kinda fixed in #103 due to changes inside transaction implementations, but the latest release version v2.0.0-rc8 released before it and when I vendor the v2.0.0-rc8 it still contains leak, maybe I am doing something wrong?

Hello, there are two PRs that fix known memory-related problems:

• 103 that merged in v1 branch with a tag v1.5.0 and
• 104 that for a main and tag v2.0.0-rc8.

I have to take several days to check if release v2.0.0-rc8 contains the same fix as 103.

Good day, Alexey!
Sorry for the long reply, I checked and the latest version v2.0.0 contains a fix for the pgx module in awaitDone memory leak, you can use this version.
