Wrong line number in error messages (off by 1)

[MaxLap]

Describe the bug
Error message when parsing is sometime off by one for the line.
For the following snippet:

package templates

templ TestResult() {
	<helloworld (required)>'
}

Running templ generate

Fails with the following: malformed open element: line 3, col 13. But that is straight in the middle of the "TestResult" name.
The actual problem (and as highlighted by the LSP), is on line 4 at col 13.

To Reproduce
Make a file with the provided error case, run templ generate.

templ info output
(✓) os [ goos=linux goarch=amd64 ]
(✓) go [ location=/usr/local/go/bin/go version=go version go1.23.4 linux/amd64 ]
(✓) gopls [ location=/home/max/go/bin/gopls version=golang.org/x/tools/gopls v0.17.1 ]
(✓) templ [ location=/home/max/go/bin/templ version=v0.3.819 ]

Desktop (please complete the following information):

• OS: WSL
• templ CLI version v0.3.819
• Go version go version go1.23.4 linux/amd64
• gopls version: golang.org/x/tools/gopls v0.17.1

Thanks, the line number is zero-based, which matches the LSP standard, but humans should probably see 1-based to match what's displayed in the text editor.
