Revert JLine from 4.1.0 to 4.0.15 to fix camel shell immediate exit (#23446)
JLine 4.1.0 introduced a new `AbstractUnixSysTerminal` that bypasses
the PTY abstraction and reads directly from
`FileInputStream(FileDescriptor.in)`.
Combined with `enterRawMode()` setting `VMIN=0, VTIME=1` (a latent bug
since 2017), the kernel returns 0 bytes after 100ms idle, which Java's
`FileInputStream.read()` translates to -1 (EOF). This causes JLine's
`readLine()` to throw `EndOfFileException`, making `camel shell` exit
immediately after printing the banner.
JLine 4.0.15 uses PTY-backed I/O (`pty.getSlaveInput()`) which handles
0-byte returns correctly, so the shell works as expected.
The fix for the VMIN bug is in JLine PR #1871 (commit 8242f965) but has
not been released yet. Once JLine releases a version with that fix,
we can upgrade again.
