feat: added option dataAttributeSalt to saltify data-attributes

[khodakova]

Description

If you are dealing with MFE and own ui-kit, you need the ability to use different version of ui-kit on different MFE's.
But on our project we encountered a problem: styles from diffrent version of ui-kit overwrite each other.

Additional context

We tried to use attribute scoped on styles, but it didn't help. This is because data-attributes are based on a hash of the component code and if the styles are in a separate file the hash doesn't change.

The dataAttributeSalt option helps to provide a "salt" to a data-attribute which can contain any value you want (for example random value or version number).

Therefore styles become unique throught the MFE even if they use different versions of ui-kit with different styles.

It doesn't sound like an issue that needs to be solved by plugin-vue. Personally, I think the styles for multiple versions of the component library should be isolated by version, rather than relying on external tools to provide a solution. You should add a version-specific prefix to the styles when packaging ui-kit.
