[opbpot] strip links from commands

[trajan0x]

Add a function to strip links from commands, as these can be annoying when pasting from other messages.

Slack links are probbaly formatted w/ mkdwn or something

To strip links from commands in the Slack bot, follow these steps:

1. Add a function to strip links:

package cmd

import (
    "regexp"
)

func stripLinks(input string) string {
    linkRegex := regexp.MustCompile(`<https?://[^|>]+\|([^>]+)>`)
    return linkRegex.ReplaceAllString(input, "$1")
}

2. Modify the Action function in commands.go to use stripLinks:

Action: func(c *cli.Context) error {
    configFile, err := os.ReadFile(c.String(fileFlag.Name))
    if err != nil {
        return fmt.Errorf("failed to open config file: %w", err)
    }

    var cfg config.Config
    err = yaml.Unmarshal(configFile, &cfg)
    if (err != nil) {
        return fmt.Errorf("failed to unmarshal config file: %w", err)
    }

    if cfg.SlackAppToken == "" {
        return fmt.Errorf("slack app token is required")
    }

    if cfg.SlackBotToken == "" {
        return fmt.Errorf("slack bot token is required")
    }

    botServer := botmd.NewBot(metrics.Get(), cfg)
    err = botServer.Start(c.Context)
    if err != nil {
        return fmt.Errorf("failed to start bot: %w", err)
    }

    // Example usage of stripLinks
    command := "<https://example.com|example>"
    strippedCommand := stripLinks(command)
    fmt.Println(strippedCommand) // Output: example

    return nil
},

This will ensure that any links in the commands are stripped before processing.
