Templ removes significant white space inside <pre> tags

[AdrienHorgnies]

Before you begin
Please make sure you're using the latest version of the templ CLI (go install github.com/a-h/templ/cmd/templ@latest), and have upgraded your project to use the latest version of the templ runtime (go get -u github.com/a-h/templ@latest)

Describe the bug
The following template:

<pre>
	command line 1;
	command line 2;
</pre>

is rendered to

<pre>command line 1; command line 2;</pre>

which is incorrect as the pre tag exists to make white space significant.

To Reproduce

go.mod

module templ.demo

go 1.23.1

require github.com/a-h/templ v0.2.778 // direct

go.sum

github.com/a-h/templ v0.2.778 h1:VzhOuvWECrwOec4790lcLlZpP4Iptt5Q4K9aFxQmtaM=
github.com/a-h/templ v0.2.778/go.mod h1:lq48JXoUvuQrU0VThrK31yFwdRjTCnIE5bcPCM9IP1w=

demo.templ

package main 

templ Demo() {
    <pre>
        command line 1;
        command line 2;
    </pre>
}

main.go

package main

import (
	"context"
	"os"
)

func main() {
	ctx := context.Background()
	w, _ := os.OpenFile("demo.html", os.O_WRONLY|os.O_CREATE|os.O_TRUNC, 0644)
	Demo().Render(ctx, w)
}

Run main and cat "demo.html"

<pre>command line 1; command line 2;</pre>

Expected behavior
The whitespaces inside <pre> and </pre> should be kept as is:

<pre>
        command line 1;
        command line 2;
    </pre>
