Documentation: Add a "template funcs" section to the API reference page

[andreynering]

I just realized the API reference page missed a section mentioning all the additional functions we implement on top of slim-sprig.

We should have a paragraph before the table linking to the slim-sprig documentation: https://go-task.github.io/slim-sprig/.

task/internal/templater/funcs.go

Lines 18 to 46 in a29e5d3

	taskFuncs := template.FuncMap{
	"OS": func() string { return runtime.GOOS },
	"ARCH": func() string { return runtime.GOARCH },
	"catLines": func(s string) string {
	s = strings.ReplaceAll(s, "\r\n", " ")
	return strings.ReplaceAll(s, "\n", " ")
	},
	"splitLines": func(s string) []string {
	s = strings.ReplaceAll(s, "\r\n", "\n")
	return strings.Split(s, "\n")
	},
	"fromSlash": func(path string) string {
	return filepath.FromSlash(path)
	},
	"toSlash": func(path string) string {
	return filepath.ToSlash(path)
	},
	"exeExt": func() string {
	if runtime.GOOS == "windows" {
	return ".exe"
	}
	return ""
	},
	"shellQuote": func(str string) (string, error) {
	return syntax.Quote(str, syntax.LangBash)
	},
	// IsSH is deprecated.
	"IsSH": func() bool { return true },
	}
