bump containers/image to v5.0.0, buildah to v1.11.4

Move to containers/image v5 and containers/buildah to v1.11.4.

Replace an equality check with a type assertion when checking for a
docker.ErrUnauthorizedForCredentials in `podman login`.

+# aec
+
+[![GoDoc](https://godoc.org/github.com/morikuni/aec?status.svg)](https://godoc.org/github.com/morikuni/aec)
+
+Go wrapper for ANSI escape code.
+
+## Install
+
+```bash
+go get github.com/morikuni/aec
+```
+
+## Features
+
+ANSI escape codes depend on terminal environment.  
+Some of these features may not work.  
+Check supported Font-Style/Font-Color features with [checkansi](./checkansi).
+
+[Wikipedia](https://en.wikipedia.org/wiki/ANSI_escape_code) for more detail.
+
+### Cursor

+### Color Converter
+
+24bit RGB color to ANSI color.
+
+- `NewRGB3Bit(r, g, b)`
+- `NewRGB8Bit(r, g, b)`
+
+### Builder
+
+To mix these features.
+
+```go
+custom := aec.EmptyBuilder.Right(2).RGB8BitF(128, 255, 64).RedB().ANSI
+custom.Apply("Hello World")
+```
+
+## Usage
+
+1. Create ANSI by `aec.XXX().With(aec.YYY())` or `aec.EmptyBuilder.XXX().YYY().ANSI`
+2. Print ANSI by `fmt.Print(ansi, "some string", aec.Reset)` or `fmt.Print(ansi.Apply("some string"))`
+
+`aec.Reset` should be added when using font style or font color features.
+
+## Example
+
+Simple progressbar.
+
+![sample](./sample.gif)
+
+```go
+package main
+
+import (
+	"fmt"
+	"strings"
+	"time"
+
+	"github.com/morikuni/aec"
+)
+
+func main() {
+	const n = 20
+	builder := aec.EmptyBuilder
+
+	up2 := aec.Up(2)
+	col := aec.Column(n + 2)
+	bar := aec.Color8BitF(aec.NewRGB8Bit(64, 255, 64))
+	label := builder.LightRedF().Underline().With(col).Right(1).ANSI
+
+	// for up2
+	fmt.Println()
+	fmt.Println()
+
+	for i := 0; i <= n; i++ {
+		fmt.Print(up2)
+		fmt.Println(label.Apply(fmt.Sprint(i, "/", n)))
+		fmt.Print("[")
+		fmt.Print(bar.Apply(strings.Repeat("=", i)))
+		fmt.Println(col.Apply("]"))
+		time.Sleep(100 * time.Millisecond)
+	}
+}
+```
