inverse search line number

I found this https://github.com/latex-lsp/texlab/blob/1f08c3a2c89631bcfca53e37ddb7c731bf6e111c/crates/texlab/src/main.rs#L48

However, in Neovim, line numbers are 1-based, which causes texlab’s inverse-search to return an incorrect line number (off by +1 from the expected value).
